More x400 Intervals

I was lucky to have company today - Chris and I did 9x400 intervals at a 6:12 pace (most were ~6:00, the last 2 were uphill and a little slower). That's 2 more than I was capable of doing last week - hopefully I can get 10-12 next week. I'm thinking I'll only do one more run this week- another jog in on Thursday morning.
