It's been a long summer - have hardly had a day below 30C for the past 3 months and almost no rain. But the rains came 2 days ago and 7 of my local parkruns within 30 minutes drive were cancelled due to local flooding of the parks. When it rains here - IT RAINS!!!! So, with a bit of a break early this morning , I went out and did a short and supposedly "easy" 4k by myself. It was only a pleasant 24C - BUT the relative humidity was 92%!! I sweated so profusely that for the last 1K I couldn't see where I was running!!!!
