One of the nice things about this time of year is that one has an impetus to seek out different types of bike rides. 

Town Run too muddy to mountain bike?  Find an off-road alternative that isn’t as sensitive to wet weather.

Not enough daylight to get your long ride in?  Get a new trainer, like I just did, and add some intensity to get maximum results out of a shorter workout.  Robbie Ventura’s videos are the best I’ve seen.

Too cold and wet to ride fast on the road?  Consider some fat tire options that will bring the speed, and the wind chill, down.

Ride your MTB on the road.  You’ll go a little slower, and maybe notice some new detours.  Or you’ll ride a bumpy or gravelly road that you’d normally avoid.

After a summer of goal-oriented riding, it’s time for exploring.
