Bad luck Ian HD`s are part of the game unfortunately!!

I find it very difficult to do hard intervals in the heat. Kudos for posting!
After some weights this am did a 30minR20. 26degrees in Edinburgh so decided to fit my C-breeze. Have left it off as it seems to mess with the drag. Anyway results below.

HR down despite the heat & this felt nice & relaxed.

Not looking forward to the next few days of heat.
