Cross Training - Grouse Grind

Hiked the Grind this afternoon in 51:21, which is a personal best. I read an article that says hiking is good cross-training for running, which I believe, 'cause this was killer. I was panting like crazy and huge splashes of sweat were dropping off me the whole way up. Next time I've just got to remember not to wear a heavy backpack and I'm sure I'll be able to shave off another minute at least!
