It didn't take long to miss a day! I was busy yesterday, doing other things, and just didn't get out on the trike at all. Doesn't matter. I'm going to keep trying to get out each day for at least a few miles.
I do have a small mechanical problem with the trike I need to solve. The chain keeps coming off one of the rear idlers. I'd left the guard off when I removed the chain tensioner and shortened the chain, so I need to put that back on. I thought the chain was tight enough that it wasn't necessary but that's clearly not the case.
