That's Fit would like to wish our very own Senior Editor Jennifer Fields good luck at the New York City Marathon this Sunday! Each week Jennifer has been sharing advice and news on all things running in her column Fit Running. So if you want to learn about which new piece of gear is really worth it, or get inspired by runners overcoming amazing odds, be sure to check it out. We'd also like to send a big "Good Luck" to AOL's Senior Home & Garden Editor Alison Mezzafonte and everyone else participating in the marathon this weekend. If you're running in the marathon, please let us know in the comments section below.
