96 days to go - A bit of a setback

Route #14 (partial) Duration : 2 hrs 4 min 55 sec Energy : 1494 KCal Distance : 13.3 miles (of 15.8) Max HR : 149 Bpm Av HR : 139 Bpm Mile pace : 09:23 min/mile Even though the weather was wet and I had an unsettled night, I set off on my first 15 mile run full of confidence. The plan was to do the run at a steady pace of around 9 min per mile while keeping my HR below 140 Bpm. Things went pretty well for the first 11 or so miles but suddenly my pace fell off dramatically and my left hip/buttock started to hurt like mad. At the 13.2 mile mark I could no longer run at all and I had to stop. After a stretching session I managed to walk home without too much further pain. Once I got home I applied ice to my butt, took 400mg of ibuprofen and had a long hot shower. These measures appear to have seen off the pain and I am relatively sure that I am not seriously injured, in fact I have convinced myself that the problem was probably just cramp, possibly payback for a decadent weekend. I will see how things feel in the morning and decide then what and when my next session should be. On the bright side, I passed my 300th training mile before things went wrong!
