I totally agree, I have varying routes that go from 50km(direct/shortest route to work) to detours of nearly 60km which take more scenic routes along our canal, a few more hills, etc. Depending if I left late or early or how I feel I'll mix and match routes, hop on or off different sections of the MUT and make my way in as fast as I possibly can. Every red light is a sprint and every other cyclist is a catch-up game. It makes things very fun(on top of just loving to bike!)
On bad weather days I'll drive in and bike the difference, usually only 15-20k. Don't want to be stuck on the highways in the rain, happen a few times but it's not pleasant.
Cheers,
Roby!
