I ran my fastest marathon in the rain.

I believe you'll develop speed via strength work which includes hill running, either repeats, or running hilly courses as the Kenyans do on a steady basis

I often lose motivation, but it's something I accept as normal.

I want to run until I can't run

Runners are the ultimate celebration people. Running is just so intense, you're really experiencing life to the fullest.

My biggest weakness as a endurance athlete has been in not drinking enough water after training, thereby racing sometimes while dehydrated.

If you want to win a race you have to go a little berserk.
