10 k race report

I did a 10 k race this morning. Finish time of 42:16 (chip) . I signed up for this race cause the last 10k a did a few weeks before Chicago was a bit short and I wanted to take advantage of my marathon training to see what my 10k PR was and to use it as a benchmark for next year. I picked this race cause it was "certified" meaning that it was presumably accurately measured to be at least 10k. Having said that, a part of me thinks the course was short which I'll get to.

I decided to run this with my HR monitor to see what it was like during a shorter race. I understand now why people put tape over the HR reading. It's useful to analyze the data afterwards, but its scary seeing the numbers during the race.

Here is my HR and split times

Lap	Lap Time	Pace	HR Max	HR Avg
1	04:00.9	06:27.7	187	179
2	04:11.8	06:45.2	190	188
3	04:20.1	06:58.6	191	191
4	04:16.6	06:53.0	194	191
5	04:25.9	07:07.9	195	193
6	04:26.9	07:09.5	194	191
7	04:27.8	07:11.0	191	189
8	04:18.2	06:55.5	193	192
9	04:37.0	07:25.8	192	187
10	03:10.7	5:07 (???)	194	191

Based on my recent marathon time, McMillan thinks I can do a 10k in 42:00 but considering I didn't run very much these past few weeks, I thought I'd be a bit more conservative and aim for a 42:30 finish though i would have been happy with a sub 43 minute finish which is what I was hoping for last time. I did the first km at 4:00 min and hit the 1 mile marker at just under 6:30 pace. Whoops. Try to slow down a bit but the adrenaline was still rushing. Km 3 and 4 are about right, but my HR is skyrocketing which was an alarming thing for me to see during the race. During the VO2Max training for my marathon the highest HR I ever hit was 186. During my one Yasso's workout, I topped out at 190. Now here I am just barely half way through a 10k race and my HR is hitting 194 and 195.

I fall into a comfortable pace through to 7 km, at which point I decide to try and pour it on. By the time i hit the 8 km mark, I had developed a nasty side stitch. I try deep breathing and rubbing it, but it ain't going away. I start to slow down and my HR slows down with it. I thought I was going much slower than I was, but it turned out I had slowed down to "marathon pace". I pass the 9 km marker and the stitch isn't hurting so much but I can feel it's still there. I hear some footsteps behind me and decide that I'm not going to let whoever it is pass me, so I pick up the pace. I sprint the last 400m with my stitch growing ever more painful and finish about a second ahead of him.

According to my watch, I ran the last km in 3:11 or at a 5:07 min/mile pace which can't be right so either the course was short (AGAIN) or the last km was mismarked. I'm leaning toward the short course since all of the previous km's looked pretty accurate and the one that was recorded to be slower I knew I had definitely slowed down because of the stitch. Considering that the course was supposed to be "certified", there's also a possibility that the course as a whole was accurate, but that all the markers were off which resulted in the last marker being off by so much.

I came in 13th overall and 3rd in my age group. Since the guy who finished 1st in my age group finished 2nd overall (BTW, I think i went to high school with him; his name looks familiar) and there was no double dipping, I was given the 2nd place prize in my age group which was a little nike tote bag. Sweet!

I may try and do a 5k before the end of the year just to get a PR time for that. I ran the first 5k of this race faster than my 5k PR so that needs to be updated with a true 5k only distance. But barring that I'm done with racing for the year. Time to go into maintenance mode to try keep from losing my gains for the year.
