hi hesh - I feel guilty that you are the only one contributing to this group! I can barely run more than 50 yards before getting out of breath, yet each year (since I turned a significant age) I swear that "next year" I'm going to take part in the London Marathon.
I would love to, and one day (maybe the next significant b/day) I will ... maybe..
Anyway, good for you. I know you do well.
