I ran my first 15 mile training run yesterday. It was interesting to say the least.
I ran this long run on a Wednesday instead of Saturday because of scheduling conflicts.
This was the first time I had done a long run the day after another run. I had done a comfortable 3 miler the day before. This was also the first time I had run a long run at the time of day the marathon will take place.
I chose this run to try a new fueling/hydration combination. Instead of only Powerade the whole way, I used water and Twizzlers. I did this because Powerade or Gatorade don't ride well and my stomach becomes upset. I've never used gels on runs but they make me queasy just trying them in a non-running situation. Gels also make my throat burn regardless of water intake. The Twizzlers/water combo did not upset my stomach at all so I was pleased. I'm not sold on changing from the energy drink though.
I said this run was interesting but here is why:
About 8 miles in my right hamstring started cramping. The cramping subsided about a mile later
At 12 miles I started running out of gas. I had two distinct moments when my brain said STOP! I can't really explain the feeling but my brain was telling me something like - hey you better stop or you will pass out or fall down. Walking for 45 seconds helped these feelings pass but when I started running again I couldn't maintain my previous pace. I didn't have any quit in me so I slogged out the last three miles and finished although more slowly than planned.
