This weekend I'm doing the New York City Avon Walk for Breast Cancer (want to donate? click here - you can still donate after this weekend, as there's a grace period). 39 miles in 2 days. And yes, of course I'll be Tweeting along the way.
I got these wonderful Brooks sneakers (now I just keep buying the same ones) at Jackrabbit Sports, where they have you run on a treadmill to test your feet (turns out mine pronate a little). The first pair were around $110, now I get a 10% discount on anything in the store for spending over $100 that first time. Excellent customer service, even if you don't run. Hat tip to my aunt Carole for recommending it to me.
