That sounds great ohoneohtwo. Best of luck with the rest of it.
RE the steps, I need to clarify that I don't run up long flights of steps- no-one does, not even the top trail runners, although they may "march" them two at a time or at least look a lot more springy than me going up them. A lot of steps are cut too high to run up anyway. My rule of thumb is that if there's fewer than twenty, I'll jog them, otherwise I'll walk.
family I have acclimatised in that I can perform better in the heat but it still feels just as hot, if that makes sense. I definitely sweat more and earlier, and my sweat is less salty, so my body has learned to retain more salts. I don't go as red, and I can also run through minor dehydration a lot more easily than I used to. I'm lucky in that although I'm quite fair skinned, I tan quite easily so I tend not to burn. I am going to be massively wrinkly though.
Didn't run today- just went to Crossfit this morning. DH is out at the moment. Just got a text from him saying the heat's absolutely killing him.
