Do you think it wil have cooled down then? I was thinking. Wold have to wait until much later in the day for it to really cool down and I don't fancy running late at night. I could wait as late as 7 or even 7:30, but no later.
At 6.30pm you should be able to find some good shade down one side of most roads. Or is there anywhere else where it's more shady? Or go out but do a shorter session (speed / hill intervals?) and make sure you're well hydrated. If it doesn't work out for you, you'll know next time to run in the morning.
Yes, it is definitely shady n one side of the road when I normally go out, I can't run shorter time as I am doing couch 2 5k and starting week 5. I was just worried about the humidity, maybe I will take a water bottle with me.
