Because it is too damn cold!
I don't mind the cold. The ice, however, I'm not such a big fan of...
As for you, perhaps a change of focus is in order. Ride more with Jane and worry less about quantity and go more for quality. By quality I'm not thinking hard and fast but more along the lines of "Hey this is fun". I hasten to add I never follow my own advice. Good luck in however you opt to deal with it.
2012 was my big re-entry into cycling. With a friend, I trained for and road a metric century.
2013, my friend moved to California, so (somewhat) trained and road the ride by myself. I finished and the time wasn't that much worse, but:
- Got calf cramps
- got thigh cramps
- Fell once going up hill
- Fell three days before messing up my headset (I didn't realize headset was slightly messed up until I was riding the ride).
- Seat angle on my recumbent was well lower than it had ever been before.
- Didn't pace myself well (known problem).
Wow. Am I good at making up excuses or what?
I rode a couple times that month and didn't ride at all the next month. The ride just kicked my @$$.
Just get back out there and ride. Ride to have fun. Ride to go to the grocery store. Ride since I can't since the roads are still covered with ice. Ride with friends. Ride alone. Just make sure that, for now, you have fun while doing it.
I started back a few months afterwards and got back into it quickly.
Good luck!
