Did a 5K in 92 degrees today. Target was to hit 35 minutes. And one minute shorter for every break. Eventually managed it in 29 min 41 seconds (9:53 min/mile pace) with two breaks. The sun was beating down mercilessly and there was no relief from any breeze.

At the end, when I sat down to take rest in the shade with water, I was getting flashbacks from that time when after a 18 mile run on a hot day, I opened my eyes to see a firetruck and firemen all around me!

My heartbeat reached 176 (which is 109% of my technical max HR). Even after sitting down for 10 minutes, the heartbeat would still not get down from 120 and I was not feeling totally up to it either. Finally, went inside the car, put the AC in full blast and took my shirt off. That cooled down the body very quickly and got my heartbeat to below 100.

Whew! I think I will try to keep these to a minimum!
