Fun afternoon at Parque Aventura, where despite 30º+ heat, I still managed to beat my best time on the black route by 15 seconds!

The problem I have going faster is it all has to be technique. My poor 49 year old heart won’t actually go any faster. Graph below shows the speedrun ringed where my heart went to 175bpm for 8 minutes and stayed there.

I did feel while I was up there that my muscles simply couldn’t get the power they wanted. Maybe I can go faster in winter when heat dissipation is easier.
