The deadline to sign up for 13 in 2013 was December 31st, but Jill Conyers has extended that to the 6th. So go sign up! You can do it!
I just added a page up there in my tab bar with all the races I'm planning on doing this year. I'll post race times up there as I do them as well. My friends and I had thrown around doing a FULL MARATHON in September, but they backed out on me. I convinced them to sign up for the 13 challenge, so now it's back on!
Oh shit. I'm running a full marathon this year.
