Invest in some good LED lights and go some night rides. I did 52 miles last night, finished at 11:30 PM. It was wonderful.
Do you guys only ride one type of bike?
Gotta change things up. Night rides, MTB, fixed gear, gravel... It keeps things from getting boring. I've been doing lots of road riding lately and so this week I plan on doing a 29 mile gravel loop in the dark just for the sake of keeping things interesting.
