The Polo Field track in Golden Gate Park is a nice smooth asphalt loop thatís two thirds of a mile around. The turns are slightly banked and not too sharp, so you can go as fast as your legs and lungs will let you. No need to worry about cars, so itís a great place to train with an iPod.
Just about every Tuesday & Thursday night for the past 2 winters I have been doing evening workouts there from about 6:00 to 7:30 PM. I have a light on my bike, which Iíll be needing starting next week, though when the moon is full I usually ride with it off.
On most winter nights I usually see 3 or 4 other cyclists out there, but sometimes on the cold or rainy nights I donít see anyone (except the homeless guys in the arch ways).
Iíll be out there this winter too, though if the rain is heavy I may just spin indoors.
I can post more detailed workouts later, but for now through November itís mostly just easy riding (18-20 mph) with 20-30 minutes of light tempo (22-24 mph), and maybe a few sprints.
Feel free to show up and join me, Iíd really welcome the company.
The Polo fields is where I got introduced into racing in the 1970's. Saw this bunch of guys in a paceline and they asked if I wanted to join in and the rest is history. Happy to hear it's still going on.
