I stopped into TriSpeed yesterday and was reminded that they hold indoor cycling sessions on Tuesdays and Thursdays throughout the winter. I've never been so I don't know how crowded it gets, or what kind of workouts they do; but given their connection with Troy Jacobson I would wager they probably do some Spinervals DVDs. I *think* they start at 6 or 6:30pm. Not a great indoor option for anyone in the city having to drive up 83 that time of day, but certainly if you are in the county or at least a little further north, it could work out.
They also still meet on Saturdays, ready to ride at 9am. I may go up Saturday the 13th.
Hope swimming's been going well, I may actually show up one of these Monday mornings now that I'm back in the water. Slow, but back in the water. Only 50 weeks til Ironman Arizona!
