Since my last post was about how to fail at running, here's a post about succeeding...on your long run. My long run last week, which was 18 miles, reminded me of a lot of things I'd forgotten since I last did long runs that were approaching the 20 mile mark. Fuel . I went years without using fuel on my long runs. Once I found a fuel my stomach can handle, it made a huge difference in how much energy I have at the end of my runs. On my 16 miler the previous week, I noticed how hard it felt between miles 8-10. I typically take a GU before I hit mile 8 for this very reason. So on my 18 miler, I GUed at 7.5 and 13. Take the good with the bad. There will be both. My first 15 miles were awesome. I kept thinking I was due for a good long run and that it was finally happening. Then the last three miles happened. They were miserable. Straight into the wind on legs that were starting to feel the first 15. I just had to remember it would ultimately make me stronger. Stick
