Where I work and live, this is not entirely implausible. Not with my bum ticker, but for someone in better condition, it would be nbd to carry a little plastic kayak or SUP down to Snowberry Creek and paddle down and across to the Sac State aquatic center at Nimbus. It would shave off more than a mile as the crow flies but not sure if the lower speeds would eat the savings. Would get an upper body workout instead of the usual bike legs. Wonder if the aquatic center has lockers or something you could store the boat. Or maybe hide it in the woods!
