what do you mean by hard and short. To acclimatize, what science tell us is 70% of max hr for 1h for 10 days in a row should produce the physiological change required to performe in hotter environement.

That is ''hardly'' high intensity. I do recommend the opposite, do your endurance session on treadmill or trainer in a hot room, and do your quality session in normal cooler temp to not affect your fitness./performance on race day. I seen some very good results from athlete living in canada and getting to kona on this protocol.

I just watched a video talking about spending time in the sauna. Much more to it than i thought

It is also a myth that you need to take extra sodium.
Dr Tim Noakes has explained all this on this forum, it's worth reading.

Assume you're talking about Rev3 FL in Venice. I live just up the road in Sarasota and will doing the Oly.

85 deg would be on the high end. Average temps range from lows in the low 60's to highs in the low 80's in early November. Humidity will still be pretty wicked, so needless to say, plan your hydration carefully.

The bike course is a bit different this year. To their credit, Rev3 volunteers have been out inspecting the course and filling potholes over the last few weeks to get it ready. The run is the same with very little shade - it can be very oven-like by the end.

The Sarasota Storm Tri Club will be there in force, both racing and volunteering so feel free to stop by the club tent and say hi. The club usually organizes some group workouts during the week, but not sure exactly what's going on for Rev3 since a lot of folks are doing IMFL the week before. I imagine some folks will be riding the bike course ahead of time. Let me know if you have any interest. Like last year, there's also going to be a practice swim on the course on Saturday sometime after the kid's tri.

Good luck, hope to see you there.

Would a dry sauna or steam room be better to prepare for high humidity?
