I had the same feelings the first time I rode (on my motor scooter) past the scene of my accident. I’ve only been back on scooter once, but I imagine if I had to do it on a regular basis, I’d be pretty hesitant, too.
Good for you on planning a trail run! I’ve got a 16.3km hike lined up for October 26th, and I have no idea how that’s going to go down. My ACL is in rough shape, and only my LCL is just about normal. Part of me thinks that halfway through the trail, one ligament will give out and I’ll have to drag myself out on my seat. Oh, well. Nothing ventured, nothing gained! (and if a ligament or two does pop, at least I can get them fixed and not worry about the bomb ticking every time I do something remotely active.
