Race temperature 21ºC / 70ºF. Using head cooling. No cool booster, just water.

I used CoreCooling during the 1/2 triathlon and I was very pleasantly surprised at how well the CoreCooling worked. Immediately upon wetting the CoreCooling band I felt a cooling effect. When running in a part with shade I even got some chills about how cold/cool it worked. When I analyzed my heart rate it remained constant during my 1h 19min run. With occasional dips which was probably due to the cooling.
