Marathon risks

A friend of mine just posted a blog entry linked to a news article about how endurance sporting events can be risky.  What most people don't realize is that if you run marathons, you have two disciplines to manage, or if you do triathlon, you have four disciplines to manage.  That extra discipline is called nutrition by many; I just call it health.

Most sane people don't just go out and decide "I'm going to run a marathon today."  For many, it takes years to get that point, with a marathon being the culmination of years of hard work.  But gone are the days where only the elite men ran marathons.  Gone are the times where only the best runners of both genders were the only ones who attempted 26.2 miles.  With the emergence of "bucket listers" in the endurance sports arena, the time from beginning runner to marathon finisher has shortened.  And anyone can find a good training plan to tell them how many miles to run evey day and when to rest for the eighteen weeks leading up to a marathon.  You could conceivably go from couch potato to marathon finisher in less than a year with little more than a pair of running shoes and internet access. Let me just say that this is a bad idea.  You wouldn't have a chance to learn running in a healthy way.

The most crucial discipline often goes ignored.  Health.  And while the discipline of marathon or triathlon may not be a team sport, entire families and communities are affected by the health discipline when a race goes wrong.


Sick or hurt
How many runners ignore pain because they want to make that race next Saturday, or make sure they get in enough miles for their training?  How many of us push through when we know without a doubt that we should take a break for some other reason that truly isn't worth sacrificing all the hard work, just to get in that last mile?  So we aren't taking care of ourselves when we're sick or hurt.


Nutrition
What percentage of people in the sport truly know how handle nutrition in training and racing?   I ran my first marathon in 2009, but my nutrition for endurance really didn't get dialed in until 2011.  There were several endurance events that my stomach reminded me that I needed to figure out a better plan before I finally figured it out.  I will say this, though:  if not for my transition to triathlon, I may not have figured it out.


General Health
How many people get a full physical, including a full cardio checkup?  Before they start running, and every year thereafter?  I remember watching the news last year and hearing about so many deaths in running and triathlon.  Many of those deaths were later attributed to underlying heart disease.

It can be heart breaking when an athlete doesn't take care of themself.  But the risks can be managed.  Athletes, take care of yourselves! Don't push yourself to keep going when you are sick or injured, learn proper race nutrition and practice it in training, and go get a complete physical!

Confession: I train 15 minutes at a time

Well, that's kind of true.  Anything over an hour, I take in nutrition.  And I start taking in nutrition early.  Recent research has led me to adapt what I'm doing, and I'll be changing my methods a bit.  USAT had a good article on nutrition myths this month that is worth a read-emphasizing the importance of individual nutrition.  Meaning-don't take the cookie cutter approach to your race/training nutrition.  What nutrition works for one athlete is not guaranteed to work for you.  But this blog is less about the nutrition, and more about what happens between the nutrition...

Read on:

For a triathlon, I'll take in a half serving of my Infinit marathon formula about 15 minutes before the triathlon starts, then I'll start with my cycling formula right out of T1 and every 15 minutes after that until I hit T2, then I switch to my marathon formula.
For a running race, it depends on the distance.  I'll take in nutrition starting 15 minutes before the race starts, and nothing else unless the race is more than an hour.  If it is, I'll take in my marathon mix every 15 minutes.

But back to my point.  I train 15 minutes at a time.  I break down my 60 minute, 90 minute, 120 minute (OH MY GOSH THIS WORKOUT IS NEVER GOING TO END) into smaller, more bearable portions, broken up by my nutrition needs.  How does this translate to race day?  I swim/bike/run from transition to aid station, or from aid station to aid station.  And that's it.  I focus on each portion as one manageable bit at a time

And the best part?  Each 15 minute segment is different.  The scenery changes, the people change, my train of thoughts change, etc. It's like my system reboots every time I take a nutrition break and I'm ready to start again.

During a half/marathon I usually run aid station to aid station and I walk through the aid station so I don't unintentionally wear my water.  The 15 minute rule gets a little more flexible, but the concept is the same, and the nutrition still happens on the 15 minute mark.

"Why 15 minutes?" a person might ask.  I've set up my nutrition to take in about 18-20 oz of water per hour as recommended and trained for, and the Infinit as directed and trained with.  If I take it in every 15 minutes, I tend not to get "sloshy" or bloated.  So the answer is "personal choice."

Truthfully, switching to Infinit has helped substantially.  No more "What was next? Gel? Drink mix? Ugh, NO MOAR," and abandoning my plan to switch to on-course offerings. I know my stomach won't revolt.  It's simple and doesn't take any extra thought.

But the race or training session is manageable.  It's not one huge event, but several smaller ones that don't overwhelm me with the thought of completing it.  Beyond that, I take one day at a time.  Ironman training for IM Texas in May? Nah.  I entered each day from the Beginner Triathlete basic Ironman plan into my calendar, and I'm looking a few days ahead at a time.  Not weeks, not even to the race.  Just to the next day or so to make sure I have time to complete the training sessions, and switch around what I need to. I did the same for the Marathon in February, and the Ultramarathon on Saturday.

The lesson is the same whether you're training or racing.  Small, manageable parts.  I've chosen to break mine up by nutrition breaks (and sleeping at night!).

How do you break your training sessions up?

Evolution of Nutrition

Ugh.  I still haven't learned how to use this blogger.  I thought it was going to post this automatically-so to my readers, I'm sorry for the delay.

I'm putting off a promised blog post about taking breaks during running to post about my nutrition.

When I started running, I was clueless.  Sometimes I still am.  I was so proud of how I looked with something like fourteen packets of Gu stuffed in a running belt during the Austin marathon...

I used Gu to keep the calories in.  On my frame, however, I took in too many calories.  Now, several years and many evolutions of my nutritional plan later, I'm still running water stop to water stop, but my nutrition is different.  None of this occurred in one huge leap, but more as a series a stumbles and hops as I (eventually) took advice of those smarter and more experienced than I.

The first major evolution of my nutrition came when I moved to triathlon.  I started using a packet of Gu before my swim, then water and Gu just out of T1 and every 30 minutes for the rest of the race.  I added a half serving of Perpetuem per hour on the bike and took in water when I took in Gu.  Essentially, every fifteen minutes I was taking in Gu or Perpetuem.

Guess what?  Still. Too.  Much.  Nutrition.  At my last triathlon, I wound up abandoning my "tried and true" nutrition plan and taking in coke on the run just to try and settle my stomach.  It was a less than pleasant experience (well of course it was, it was a half ironman, silly) and I vowed not to repeat the nutrition portion.  But since I'm gearing up for Ironman Texas and a marathon and........   Anyway, I had to figure out what I was going to replace my defunct nutrition plan with.

Enter Infinit.  (Can you hear the angels singing?)  I'd been considering switching anyway.  I was tired of all the gels, all the mixing, keeping it straight on race day, and trying to figure out where to put all my gels (There's a joke there..) So I logged onto the Infinit website, ordered an initial consultation, and waited patiently.  The slider thing on the front page didn't do much for my Type A personality because (are you listening Infinit?) there are no numbers on the sliders to tell me what exactly is in my drink at each step of the way.  Okay, I'll wait for a real person.  And of course, I'm a typical athlete.  I know what I need, I know what's best for me, just set it up so I can do it the way I've been training and let me order it!!!!!!  Yeah, about that.....   I got a email from Laurie asking me some basic information about what distance races I usually tackle, how heavy do I sweat, do I have any GI issues, my, ahem, weight......  In a pretty short period of time she had two formulas set up for me.  One for running and one for cycling.  I looked at the nutritional values and (drumroll please)......

Are you kidding me?   How am I supposed to run on that?  My pet dog couldn't run for an hour on that, let alone me.  But her email was so convincing, so I decided to give it a try. I ordered my first bag, a cycling mix, and I didn't just settle for any test.  I put it to a real test.  I set out for a 52 mile bike ride.  Hills.  Sustained climbs.  Wind.  Heat.  With no backup nutrition.  Just me, my bicycle, Infinit, and of course my cell phone, just in case my stomach decided to revolt and I had to turn my bike ride into a sudden duathlon involving a run for the treeline away from the road. 

What happened next was pure magic.  No stomach upset.  No bonking.  I felt strong, I felt good and my bicycle had wings that day.  Okay...  I'm convinced...  Slightly.  Let's see what happens when I run.  Surely this is a fluke and can't happen twice. So I ordered a bag of the running mix.  Once again, a real test.  Fourteen miles in Texas heat.  Once again, magic.  Now, don't get me wrong.  I'm not just taking my word for it.  I'm putting it to the test.  Again.  And again and again.  And we'll see what happens.  But through this whole process, Laurie has been amazing.  She's been patient with a Type A athlete who is demanding and not understanding.  I just run this, I don't do the whole microbiology thing where you need to understand exactly how muscles/cells/organs work and work under the stress of endurance exercise and then how to feed them.  I mean really, who has time to do all that?  But I'm glad someone does!

So I'm still taking in nutrition every fifteen minutes, but not at the higher levels of calories I was taking in before.  Laurie dialed it down for EXACTLY what I needed.  She seems to be an expert or something!!!  She asked the right questions and got the answers she needed so that my hypersensitive-going-to-need-counseling-before-this-season-is-over stomach could handle the stresses I'm putting my body through.

And that's the foundation behind Infinit.  The formula is designed with each athlete in mind.  How many calories, how strong you like your flavor, how much you'll be sweating, how much caffeine do you want (if any), do you have any gi issues, etc.?  Infinit knows you aren't just another athlete with a number.  You're an individual with different needs than the ones that you're racing, and I really got that feeling throughout this whole process.

So, Thanks, Infinit.  And Laurie...  Standing ovation!

Infinit has goodies like energy drink mix and recovery drink mixes, water bottles and hats.  Don't forget that when you order from Infinit, you can help to fund the scholarship by using the discount code "firegirl" at checkout.

To my readers-I hope your holiday season is going well.  Happy New Year!

Hydration Equation, What's Your Situation?

Hydration math...

Yep.  That's about how it can feel sometimes after a discussion of hydration math.  With the drought and the fires in Texas, I thought I'd take a moment to put a few words in on this very important subject.  While not everyone needs to worry about it during a race, everyone should be considering their hydration status during other times.  Proper hydration is important because it can affect your performance, helps lubricate your joints, helps your body recover, and even affects cognitive function.  There is so much that proper hydration does for us, that to list it here would take away from the intent of my post.

Let's start with how much fluid you lose during a training run.  I'll use an example from a discussion held a few months ago...

First, a important message from our sponsor, Water.  Water equals a little more than 8 pounds per gallon, so 1 pound is about 16 ounces...  Keep in mind, the math gets a little fuzzy and I round for simplicity and to eliminate decimals.

Say you're a 155 pound athlete that went for a 8 mile run in 100 degree heat, you drank 24 oz of water and it took you 81 minutes.  Weigh yourself naked before your run.  Then weigh yourself after your run, also naked.  For our example, you lost two pounds.  155-153 is 2 pounds of hydration loss.  24 ounces of water taken in is about a pound and a half.   Add that together and you lost roughly three and a half pounds of fluid.  3.5 divided by 8 miles is .4375 pounds of fluid.  A calculator helps me find (16 oz per pound, so 16 times .4375) that .4375 pounds of fluid roughly equals 7 ounces per mile of fluid loss.  I prefer the per mile measure rather than per minute because it tends to be more constant through the different speeds we run and easier to figure than using per minute.

So, you lost 7 oz per mile of fluid through sweat, exhalation and other normal body functions.  This is good to know.  But these numbers may change as the weather changes, as your exertion changes, and even as you become a more finely tuned athlete.  So, for endurance athletes, weight is your best measure for hydration information, and as you get more familiar with this method, you'll be able to predict where you'll be.

Okay, so I lost a billion ounces of water on my run this morning.  Now what?

Now, you replace it.  Not at once, but gradually.  Evidence shows that your body can process about a liter of water per hour.  If you drink more, you risk affecting your electrolyte balance.  Want to your body to get the most use of that expensive bottled water or sports drink?  A liter per hour, max.

So what does that mean for me?

It's all weight based. The minimum amount of fluid you drink every day should be one half your body weight (pounds) in ounces of fluid every day.  So, if you still weigh 155, then you should start by drinking 78 ounces a day.  Then, you went out and ran for 81 minutes.  Replacing fluids by weight lost is the preferred method.  If you know how much weight you lost during a workout, attempt to replace that much fluid  (16 ounces per pound) in addition to your minimum daily intake.  Since in our example, you lost 2 pounds, drink at least 32 ounces of water (at a liter per hour).
If you don't know how much weight you lost during a workout, start with the following formula:
Hours of training x 32 = total fluid.  Total hours of training is how long you should spend rehydrating following this method.  In our example, you ran for 1.3 hours, so drink at least 42 ounces of fluid at a liter per hour.

Real life application (in a bubble)

Now it's time to apply the formulas.  You got up and ran this morning, as soon as you got up.  You weigh 155 pounds, so you need to drink a minimum of 78 ounces a day of fluids.  You lost 2 pounds during your workout, so you need to replace 32 ounces of fluid (16 oz per pound), but don't forget the 24 ounces of fluid that you drank during your workout.  78 + 32 + 24 =  134 ounces of fluids.

I want to point out that recent research points to sports drinks, certain teas, juice and other fluids being acceptable for hydration.  Caffeinated drinks aren't the hydration nemesis they were once thought to be.  However, hydration math has its limits, as it cannot predict sweat rates in different weather conditions, differences in individuals and other wrenches that get thrown into the works.  Your best gauge is the color of your urine.  If you are peeing clear to light yellow, all signs point to well hydrated.

Having said all the above, you'll need to find out what works for you.


Electrolyte Replacement

I also want to mention sodium.  I've spent several years researching, practicing and seeing what works for ME.  You'll need to find out what works for you.   Don't forget potassium, calcium and magnesium either-these are also crucial to proper electrolyte balance, proper muscle contraction/release, and for life.
