I've run in Italy in the summer and after a week or so it started getting easier, but then I came home and it was August and 15c FFS so then you lose any benefit and if race day happens to be freakily hot then you're a bit stuffed. You're right, you do adjust to different temperature ranges over the seasons.

If you want to read loads about it, google 'heat acclimation'. It's what the 'merkins call acclimatisation for some unknown reason

mblnFERCr Jun 2015 6:53pm, 26 Jun 2015 704 posts	0 mblnFERCr The suit is cool (ahem), but I think the take-away from most articles is expect to do less well when it's hot, even with acclimatisation the stress on your body is increased - so be good to yourself
J2R Jun 2015 9:26am, 30 Jun 2015 105 posts	0 J2R I'm booked in to do a city centre 5K race late Saturday afternoon, and the temperature is forecast to be 27C! I think I'd better get started on the heat acclimation/acclimatisation (please delete as appropriate)..

mblnFERCr Jun 2015 10:11am, 30 Jun 2015 711 posts	0 mblnFERCr Suffered pretty badly wth heat at the Giants Head mara on Saturday. After the first 8-10 miles I just had to back off. The humidity was the real problem, my shirt was soaked, but nowhere for the water to evaporate to. This article may be better than the RW one : http://www.theendurancestore.com/blog/blog/2015/04/28/beat-the-heat-this-summer-part-1/. But I guess with the RW one you could also beat your 5k pb in 5 easy seconds or summink
J2R Jun 2015 1:41pm, 30 Jun 2015 106 posts	0 J2R Yes, humidity got me too at the weekend. I was well down on my target time for a 10K. I knew it wasn't going to go well when I was already a bit sweaty and uncomfortable just doing an easy warmup jog around the playing field before the race. Maybe I'll be lucky enough to get drier heat on Saturday.
