Take a LOT of water, make time in the morning when it's cooler. Watch your HRM if you have one. Good luck!
Ruth, you trying another 50?
I am debating. I only have three rides left this season, and since I want to complete a 50 this year...I think this weekend I will play it loose, see what the start time is and how many are entered, and decide from there tomorrow afternoon. Temps are still forecast high 80's/low 90's.
