I suppose various parameters affect the answer to this question, like how fit (and how fat) you are, how well hydrated you are, how hot it is... but, I'm still keen to hear what people have experienced? What kind of drop-off in speed/performance would you expect if you're cooking in the high 30s?? And should you stick to HR targets for hot weather training rides, or adjust upwards? And then how do you handle these kinds of conditions when you race??

If you have ever ridden 94.7 and had a late start or done IM70.3 in EL when you run during the middle of the day then you will never dispute the heat has an effect. i tend to think it hits you at once as opposed to a gradual slower pace/difficulty over the course.

Its all trail and error.

 

Here`s a scenario - my brother and I - same height but he is 107kg, Im 84.

 

Racing in 25 degree heat - I take 1 bottle an hour, he takes 1.5

 

Racing in 35 degree heat - I take 1.5 bottle per hour - he takes 2.5 + gel

 

You need to make sure you stay topped up!!! Even in cold you need to eat/drink more as the body uses energy as "firewood"

 

No real formula I know of but try to spot the signs before they happen - hence trail & error. All about knowing what you can do and how hard you can go before blowing.

 

Personally - I go better in the rain for some reason.

 

Listen carefully to your body!!!!

 

Hope that helps!

Heat kills me.

 

Each to their own - but when it's hot, it's as if I'm trying to sling a rather overweight, dead buffel along with me up the hills... Cool weather and I feel like I can ride forever...

!! Maybe I was the dead buffel... going to larf my sox off about that on my next overheated ride!

Sure, VdB, definitely helps to train to those conditions... I do late morning and lunch-time rides a lot but funny thing is this year has on the whole been a lot cooler where I am. But... had some 'fun' on real scorcher of a ride this weekend, saw my average speed dropping and felt sluggish (dead buffel) on my next ride which got me thinking...

What I did find works a treat is to take a frozen water bottle in your back pocket as it stays cold much longer than on the bike. And cooling your legs with water...

Heat has a big effect. When doing brick sessions I always try to do as many runs as is possible late in the day to simulate the real thing. The more you get used to it the better you handle it. Still sucks big time though. I find everything slows down in the heat. I started 94.7 in 2010 at about 10h30 boy was it hot and what a shocker of a result compared to my 07h30 start in 2011. Completely different results.

 

When you jump into the oven for the first time its gonna come as a hell of a shock.

I use the water on my legs trick, and through my helmet onto my buff. I also take a bottle of frozen drink/water and put in in an old sock before putting in the cage, keeps it colder just an hour or so longer but worth it! I also try to do some rides in the heat of the day, although for me personally I find the 5pm heat quite draining as opposed to 12-2pm heat.

My coach assisted in a study as SSISA for this exact thing. There was somthing like a 15% drop in performance between 15 degrees and 35 degrees over a 40km TT.

That'll obviously vary according to personal fitness, weight, etc etc etc!

Personally I feel like I die in heat, but I do cope alot better than most. So it's all relative I guess!

I did a 48hr adventure race this weekend in the Nothern Cape. Temps reached 30deg by 8:30 in the mornings, peaked at around 40deg and dropped to 30deg again only at around 7pm. At least the humidity was low. The first day I really battled, but the second day I felt much better. I think you must get used to the heat. As simple as that.

weather can be your enemy or your friends, wind and heat is your biggest worries. i presume that you are talking about the Argus, this time of year. if you one of the late starters you have to worry about heat, and drinking. wind can slow you down a lot unless its a tail wind then it helps you. cross winds can cause accidents.
