My car has air con but 2¼ miles? It won't be efficient and the last thing the air quality needs is another short-hop polluter. I'd ride in full-on bimble mode, climbing very gently and walking if any climb's that severe. Oh and pack the mini body spray (which reminds me for this evening's ride...) I don't understand ft/mile - what are the %s?
I went in the car, and as you suggested it took longer than 11 minutes

Here's a metric profile of the route I would have cycled though.
