I’m running for 50min - 1 hr in the heat now and it’s killing me!
That said, I have made the decision to stay with the high-heat workouts. I feel like sweating cleans out my system...and hopefully it will improve my conditioning.
Yesterday I backed off the exertion a little, adding some little intervals, but saving my high intensity intervals for near the end of the ride.
The nice thing about biking is I have plenty of water or Gatorade available.
