Since it's only been a week since I did a 62-mile ride for charity, today seems like a good day to try for almost 90 miles, right? LOL. We'll see how it goes. There's a decision point at around 34 miles, where I can either add on a nice 22-mile there-and-back rail trail, or not. But once I get to the end of that outbound segment, everything else is "turn around and go home". It's basically either 68 miles or 90. There's a commuter rail line along part of it, but it's closed Sundays for track upgrades.
I predict many donuts along the way. Shut up, it's easily digestible carbs. ;-)
