This challenge of running two half marathons in one weekend was certainly a learning event and an experiment. This post is about what I did leading up to the back to back races and also what foods I ate (and should have ate) between the two races.
Back to back race prep
Leading up to this double half marathon weekend I took some measures, also because I was going for a specific goal on the first half.
My training had been going well, and I was familiar with the course for the Livermore half so I thought it could be a PB so I wanted to do whatever might give me an advantage. This included:
- Sitting at work and standing rarely (I stand most of the time, typically)
- Stretching my legs (hams, glutes, calves, hip flexor) at my cube 3x/day and put Kinesio tape on my calves to loosen them
- I fueled properly the day before
- Two days before I restricted (not sure if that was a benefit)
- Observed two days of no running leading up to the first half
- In the evenings on the two days of rest, I stayed off my feet as much as possible
- Ensured plenty of rest leading up to the half
- No drinking alcohol the week prior
- Drank plenty of water (thanks to nuun!) the two days leading up to the races
- I took a low dose of magnesium
Fueling in-between back to back half marathons
Fueling is important when running a half marathon, but what if you are running two halfs within a 25 hour time period? It takes 24-48 hours for food to be stored as glycogen for muscle use so basically you have to start eating during your run or right after! But at the same time you don’t want to be full for the race the next day. The goal is to eat simple, low-fiber carbs (high-glycemic index), which convert quickly to energy in between the two half marathons.
Here’s a listing of what I ate after crossing the finish line of the first half marathon and before I went to bed. You can see what I ate the morning of the second half marathon on my RnR SF race report.
- 1/2 Kind bar (I couldn’t finish it because my body was not interested in that right after the hard effort)
- Sweet potato casserole
- French Fries
- Purity Peach drink
- Kidz Clif Protein bar (peanut butter)
- 1/2 package Pro Bar Bolt without caffeine
- 1/2 kids clif chocolate chip bar
- Corn bread with a little butter and strawberry jam
- Zucchini bread with a little butter
- Homemade Oat bars
- Carbonated water with real lemon juice and splenda
What I learned through all of this is that next time I will plan a little better regarding fueling between back to back half marathons. (And yes, there may be a next time! I’m training for my first full marathon in Sept.) Here is a sampling of what I learned through this:
- I didn’t eat even close to 2000-2600 calories between the finish line and the start of the next race.
- I wasn’t hungry at 3:30am before race #2 but by the time I got to the starting corral I was starving and my tummy was audibly rumbling. I was concerned about putting more gels (sugary substances) in my stomach and whether it would hold up (it did!).
- I didn’t plan ahead of time the list of simple, low-fiber, high glycemic index carbs that I should eat, so I just went with what I felt like eating, which wasn’t much.
Items that were on hand in my house that could have been part of the fueling plan:
- Apple sauce
- Kidz Clif bars
- Recovery powder drinks
- Blueberry smoothie
- Candy: skittles, starbursts
- Gluten Free Bread
- Tator Tots
