I did it, I enjoyed it, I did the 10km in 54:53 which is a PB, and finished the 15km in 1:26:57 (possibly a minute or so quicker due to the phone freezing at 1:22 (14.3km) and not coming back until I was indoors).
Now its a couple of hours later and I'm still aching, and still feel shattered, but I know I did it, and I know I pushed myself, and I didn't puke which means I could probably do more in a race situation. Roll on next Thursday (I'm not daft, once a week will do for Janathon, no point injuring myself).
