Run ...

Great run today! I was afraid I was going to be relegated to the treadmill due to the storms but after 5 - 10 minutes of pouring, it stopped. It's now started again, with rumbling thunder and all. But there was about an hour break. I'll run in the rain and I've been stuck miles out in some really heavy rain but it was coming down too hard to really start out for awhile.

Anyway, 38 minutes, Trolley Trail to Gregory. Felt good. Knees good. Of course I have no idea how fast or far I run ... Did my hill acceleration up 58th st. The TT is flat but I've got to go down a short steep hill to get there and then back up. So at the end of most TT runs, I like to try and accelerate all the way up the hill. For fun! Well maybe not on runs over an hour or when it's really hot.

Which reminds me ... the danger of heat and humidity .... It wasn't that warm when I went out, ~70 degrees, but it was thick, RH ~70%. No sun, though. I felt fine the whole way but that's getting up to the point where you need to be aware of the heat, because heat and humidity can be really dangerous. No matter how fit you are. The humidity has never bothered me much and with the cloud cover I was comfortable, dripping sweat but comfortable. Hopefully I can build up some heat acclimatization in the next few weeks before summer really sets in. And I avoid running when the sun is high in the sky once it really starts to heat up. The humidity, of course, adds to the danger, as your sweat cannot evaporate and cool you.

I guess the rain is good for the grass. But I'm hoping to be able to ride singletrack next week sometime .....

I am so glad you got a run in and that your knees felt good!!! How did they feel in the morning?

Interesting about the humidity not allowing your sweat to evaporate...never thought about that. How hot is too hot to run outside do you think?

Temperature depends on the person. You'd want to avoid the hottest part of the day, of course. You won't have the humidity issue there, so your mornings and evenings will be cool.

You can build up some heat tolerance but it's still dangerous. Usually it's the heat and humidity combination. But definitely back off in the heat and stop if you start feeling really bad.
