https://photos.app.goo.gl/7cEesyUZsq2CqAs9AAnother attempt at the 2015 Billygoat, but I couldn't finish it because I kept getting cramps in my hamstrings. I started getting them about ten minutes in and had to run very slow to keep it from getting worse.
But then on the way to 18, I couldn't run more than 10 steps without getting another cramp in my hamstring. So instead of hobbling through the rest of the course, I just stopped there.
I have no idea how to resolve this. I stretch and strengthen my hamstrings, but I continue to get cramps on long distance courses.
