Even the gradual running program on the treadmill and trails was a bit much for the joints, so I've backed off of it. I won't be running the 5km on Dec 22nd. It'll be broken running or a 1 mile walk. I've kept walking and riding though. I plan to reboot the running program back at the beginning, skip the treadmill altogether and keep it on the trails. Outside's nicer than the gym anyway.
Yesterday as a great hike after dark up Badger Mountain with Rocky a.k.a Barky, Barktholomew, Barkimus Maximus, Sir Barksalot etc.
It was below freezing, dark and late enough that we wouldn't run into people on the trail. Perfect given Rocky's friendly-but-aggressive-looking behavior. We headed up. The trail was snow covered. I had my headlamp and the fist-full of light; but, needed neither. Plenty of light from the city reflected by the snow. The trail was compact snow, so fairly slick. Rocky had no problems and neither did I, unless I looked far-field while trying to walk at the same time. We walked up through a small cloud - a typical winter day has the local hills each capped with a cloud, so no surprise with the cloud. The city lights were evident. The new shopping areas were totally lit up, neighborhoods less so. There was a dark patch which is an orchard, undeveloped so far.
I never saw a coyote or rabbit, although a few times Rocky stood at attention and looked in a fix direction in the distance. I never was able to see what captured his focused attention. He had a blast - running off the trail in all the interesting directions I don't walk, since the guidelines for humans are to stay on the trail. I'm thinking he covered about 4 times the distance I did. He's social and does a good job of staying in contact while running all over the hill. So, we crested the hill more or less together and then headed back down. No physical issues. A great walk in a winter night.
