Intervals

I did my first “proper” VO2max session yesterday. The aim is to increase your maximum oxygen intake, and to do that you run intervals at up to 98% of your max heart rate. I don’t have an athletic track, so I had to have to guess the distance of 600 meters. I did 5 repeats, as ordered in the training plan, and it went ok, with my heart rate up to 182 – I can assure you, that is rather high. I felt a painful twinge in my hamstring for the 36 hours after that, but it seems to be ok now.
I definitely have to be careful with my shin splints, I could feel the by now familiar pain in my left leg all day today, so I decided to skip today’s 11 miles run. I will probably do a run on Friday, and then a long one on Sunday, that would still leave me at about 35 miles this week, which is significantly less than in the weeks before my injury. I am obviously guessing wildly here on how much mileage my battered leg can take at the moment. If the pain gets worse it means I’ve got it wrong.
