Switched to half mile intervals instead of quarters. There's just hardly any endurance aspect to a quarter. Which I already knew but I guess forgot or something. First attempt at half miles I averaged about 3:39, every six minutes. Third attempt I averaged 3:28 for 2 miles total. But only every 7 minutes as I went with my 8 year old nephew who averaged over 5 minutes per.

Top of right foot is hurting a bit from the vibrams. I've put them aside and am back to normal shoes for now. Probably should take time off but that's no fun. Instead a bit less mileage. Landing on heels for now. Knees are good.
