I will try and ride may age this Friday. I did 36 miles on Monday. I would have done more but I had to get home and cook supper. Temp was in the 90's but I'm OK with heat. I drink and sweat A LOT. I only average a little over 10mph. Never stopped for more than a minute of so. I don't think 52 miles will be that difficult. So far my longest has been 38 miles - again, all in one ride without resting more than a few minutes.
I've been reading everyone's posts about riding centurys. I'm not ready for that. But I am getting tips from you all.
I rode about 12 miles on the other days this week and I'm going to rest up tomorrow. Then I plan on being on the trail early Friday morning. They are forecasting a high in the low 80's so that should be good. Wish me luck and thanks for all your help!
