Someone on this forum (don't remember who...) said something that kept me motivated to ride throughout this last winter. It was this: Just plan to go out for a ten minute ride three or four times a week. I found that if I just went out for a casual "spin around the block" I would just get caught up in how FUN it was to be on my bike and it would turn into a much longer ride. If you are anything like me, you might get caught up in all of the steps that need to happen in order to get out and do a "proper" bike ride; packing toolkits, packing extra tubes, packing water, checking tire pressures, finding this and that and whatever.... I tend to pack like I'm summiting Everest for some reason. But with the 10 minute directive, I'm not getting all hung up on all that stuff. I just grab the bike and go. I do hope you get your motivation back in any case.
