Notes
Failed attempt at 20 miles. My head wasn't in it today and I've been weak since returning to the US because of moving. The humidity was also just too much. I ate two gels and drank a lot of water, but it wasn't enough. Around 12 miles my right leg started hurting behind the knee - maybe lower hamstrings. I don't know if that was cramping or an injury, but it didn't seem worth slogging through 4.5 more miles slowly when I stopped. I think this settles the debate: humidity is at least as difficult as hills.
