USAF Week 7 - Long Run

Duration = 2:28:49
Distance = 8.34
Calories = 1249
Max HR = 161
Avg HR = 143
Running Index = 36
Max Cadence = 94
Avg Cadence = 69

Sunday: long run
Equipment: Asics Gel-Cumulus 9s, shorts, tech shirt
Conditions: >90F and 50% humidity at the start, some wind from the south that was mostly screened by trees

Warm-up: 5:00 walk
Main: balance of 12 miles with heart rate 130-140 (that was the plan)
Cool-down: 5:00 walk

I knew pretty quick that Plan A was out the airlock. What I settled on was run/walk til dark and call that "good enough". I would try to run near 15:00 pace, but that developed a higher than desired heart rate. I set a limit of 160 at which point I would walk until I was back in the mid 130s. The caused a lot of walking as just walking was keeping my heart rate in the 140s for quite a while before it was finally drop to my target. I used this run outside to get an idea of distances around different "blocks" near where I live. I now have a known route this is ~5 miles around. There is a convenience store on this route that I can use if I need something before I pass my house. I still need to gauge the larger available "block" to determine its length.

This was hard enough with the Polar HRM I use adding its own challenges to the situation. It seemed to loose steps occasionally. This impacts total distance, pace, and cadence. When I'm running I tend to be very consistent around 90 strides/180 steps per minute. When the reported cadence is in the 50-60 strides/minute ranage, I know it is whacked. I didn't run with the GPS sensor today, but that has its own issues. The Polar uses the stride sensor for pace/distance as the priority. It will only use the GPS for speed/distance if the stride sensor is not reporting. I would prefer to have the pace/distance to come for the GPS if it is available while still recording cadence.

Just seeing the temperature made me tired.

I'm impressed you were able to keep your heart rate that consistent in such heat - even if it was higher than you had planned.

That's cool that you could relate to my post as you have a similar experience in south Louisiana. It was a really emotional run for me but it was cathartic.
