Argh. Forgot to plug my Nike+ sensor back into my ipod after syncing, and I didn't realize it until I was on the treadmill.
I bumped up to Week 4 today, and it was hard. But I DID IT. I gave myself an extra 30 seconds to walk before the last 5 minute run, but I think that's probably ok. =)
Still walking at 3.9 and running at 4.8.
