Kemback is about 40 minutes pedal from St Andrews & has lots of fun trails. I’ve not been up since February though (post ACL reconstruction) so I can’t say what’s open at the moment.
The bike shop in Pitscottie is closed though.
Storm Arwen made a mess of a lot of the trails in Tentsmuir so it could be a wasted trip and it’s flat as a pancake.
There are a few trails tucked away in Cairngreen Wood near Cupar, quite short but could be tied into a Kemback ride.
Pitmedden is 45 minutes away by car.
