Throw a bike into your vehicle or on a bike rack. Drive to Banker’s Hill area north of downtown. This is 5 to 10 minutes away from your destination, a bit more on the return (uphill).
Best to use a small, cheap, urban-type bike and a big lock. If no bike rack at hotel, lock it to a railing inside parking garage.
Its all free, and with this weather you won’t even get sweaty. I’ve done it a lot.
