North of Houston, we have had 50+ days with temps over 100 degrees. The humidity is also high, often 70 to 90%. I am soaked with sweat, even before I get on the bike. It has not stopped me from my daily Clyde ride of 17 to 25 miles. I just make sure I stay hydrated, before, during and after the ride.
Got up at five-thirty this morning, and it was already 78 degrees.
