My previous 5k PR is about 27 minutes (keep in mind I weighed about 255 and weigh 242 now) I figured I should be able to put a decent dent in that time. Due to my lack of training, I've never actually trained for a 5k other than my first race ever, I figured I'd just go out at a sub 8 pace and hold on as long as I could.
I managed 7:53 for the first mile, however it was all downhill. The second mile was rolling hills but had a decent incline that slowed everyone down. Mile 2 was 8:15. After that my legs wouldn't move as fast as I would have liked them to and I slowed to about 8:20 or so, then it was back uphill which killed me...my third mile was 8:45...my heart rate was SOARING. I don't think I've kept it above 160 for that long. The finish was flat and I managed to pick it back up...not as much as some people but, I didn't plan on having much left at the finish.
25:54...Can't complain too much. Now I just need to knock off another 4 minutes by next April.
Then I ran back to the start to get my run in for the day. I suppose I'll go with a "Shit Triathletes Say" reference as the reason I didn't break 25 minutes...
