I rode Ottawa to Richmond and back this morning. In general, the trail condition was great. There were only 2 things that you need to look out for.
1) Between MM 63 and MM 64 the are two cracks in the middle of the trail about 6 inches long and 2 or 3 inches wide. There are not going to swallow you up but might make yo lose control if you are not paying attention.
2) 1/2 a mile north of Richmond there is a downed tree. It’s an easy portage and you can see it from a long way off.
Hope these help.
