I'm mixing in a little roller blading, ice skating, running hiking on top of 5-10 hours on the bike but have been recovering from Covid that I got Thanksgiving weekend. I figure some variety is better than nothing if the roads are bad. We have snish today, so, I went ice skating. If I wasn't so damned old, I'd play hockey. But I lost a month due to Covid and it will take me two months or more to get back to where I was. Until lungs aren't hosed, no intervals and nothing higher than low zone 3. Not optimal but better than nothing. I'd hire a coach but I am uncoachable.
