I've actually been riding inside for the last month because of life and work getting in the way of outdoor riding.. I've got a couple of cyclocross races in the upcoming weekends and then I'll be getting my fatbike out for winter riding.
I need to fnd the right outfit to wear so I can bike more this winter. Especially some good gloves. Once it drops below 20 degrees I switch to running, which isn't fun at all. If there's enough snow I xc a couple times a week which keeps me in great shape for skiing.
Summer sucks compared to winter...in all ways.
