Last Saturday I ran another half-marathon. This one was quite a bit flatter than the last one, something which made it a lot harder on my cardiovascular system but also made me much less sore afterwards. I somewhat overestimated my preparation and didn't pace myself that well, so I didn't beat my old time. However I still made it in under two hours, 1:54 on the nose.
If I'm going to keep running these things I reckon I should adjust my training program to include more strenuous, shorter workouts. Currently I've been running extremely long distances but rather slowly; my sense is that I need to work on speed more. Any advice?
