It's got warm all of a sudden in our part of the world. It takes a couple of weeks of consistent exercise in the heat to get acclimated.

Did you weigh yourself before and after? Do try that.
This makes sense, last week it was in the low 50s and raining - I was wearing my warm cycling clothes! I just wasn't sure if the chills meant anything, I thought it likely did. I also tried two intervals last night to see what it felt like on the bike-bike rather than the spinning bike. I should probably wait to get acclimated to the heat first.

I am, however, surprised at how good it feels to ride in the heat - especially when I am going fast enough for a breeze. I have never been a lover of the heat, so this is a good development. Either that, or I like riding well enough that I am going to enjoy whatever weather I can ride in
