60 miles the other day. Scrubbed the last 5 miles because I saw it was raining around summit, the steepest, most dangerous part of the route. I've descended that part before in wet conditions, absolutely scary and dangerous and I'm not going to do that again!
The danger in those parts comes from either myself skidding and crashing into trees or rocks or vehicles or falling into the ravine or an incoming motorcycling skidding and colliding me.
Today, just a couple miles commute to and from the park and then doing 2 hr jog on the park. First time I jogged that long and never been this sore, not since last year, I can barely walk! Surprisingly, I did not have any problems getting home riding my bike and wasn't any slower. It would seem the muscles involved in jogging is different than cycling because my "cycling muscles" aren't affect and my cycling performance is unaffected.
Anyway, it's way safer to jog on the park. The walking paths are totally isolated from vehicular traffic and way cleaner air from the many trees. It's such pleasant experience, more relaxing without watching out for traffic, potholes, and exhaust fumes from vehicles that I'm thinking of offsetting my long rides on Saturday to make time for jogging. The environment is way cleaner too. No garbage, no litterbugs in the park. I could probably ride my bike in the park but there's so many joggers that I'll have to be much slower, I'd rather just jog if I can't do higher speeds.
Strange how muscles act. Years ago before I met my wife, 22 very active. Many sports and weight lifting.
One girlfriend asked me to go walking with her. 1 mile uphill 2% grade and back. I was sore for a week.
When I can't ride anymore, I'll take up walking. Good exercise.
