Even though I have kept my run training mileage high, between 15-18 miles every Saturday, I was a bit leary of signing up for the 50 Mile race at Iron Horse. This was a great opportunity to test my fitness for ultramarathon events.
We had planned to run on Saturday but a cold front pushed through early Saturday morning with rain and thunderstorms so Sunday looked better even with the cold. It was 38' under a clear, full moon sky when we started our run at 6:00 AM. Even with the headlamps, we proceeded slowly at first until the sky lightened at 7:00 AM, before a spectacular sunrise appeared. Using the Sand Lake parking lot (with restrooms) as our starting point, I had laid out a 7 mile trail loop that featured both service road and singletrack followed by a 4 mile asphalt road loop.
I stayed well fed during this experiment, using four 250 calorie bottles of Hammer Perpeteum, one 330 calorie bottle of Hammer Sustained Energy, 4 Hammer Gels (90 calories each), including a Espresso near the end with 50 mg of caffeine, and a Clif Builder's Bar that contained 20 g of protein along with 230 calories. I also took Endurolytes and Anti-Fatigue caps all day.
Post event was my usual bottle of Hammer Recoverite and a light meal with lots of water. The Garmin, which tracks not only speed and distance but also elevation changes, showed I burned 4,210 calories while consuming 1,920.
