hi spinner

Well, you have 2 months to go still, so it is certainly possible to get yourself into some kind of reasonable shape for the ARgus. Cycling is not like running, where you have to really allow a long build up period. In cycling, it's really just a basic level of fitness that is required and you will be able to tolerate the ride - you wouldn't be in the shape to do a good ride, and the hills will prove diffcult, but Argus is a fun ride, and so you will certainly have time enough to get to that level.

I think spinning is a good option, aside from riding on the road. I really do think that you need to consider doing a few rides on the road, just to become more accustomed to riding. It's especially helpful if you can get out and do a ride in a group of other cyclists, so you learn what it's like to have bikes around. The Argus is not a lonely event! You'll have hundreds around you all the time, so the sooner you learn to relax with that, the better. And the only way is to actually ride with other people. So I really woudl suggest that.

As for the spinning, three classes a week is the best bet, for now. Those classes are about 45 minutes long, and you can pretty much regulate the intensity. Obviously, spend a couple of weeks in the easy/beginner classes, and then 'graduate' to the more advanced classes. I'd say by mid-Feb you should be doing the intermediate classes. And then on your weekends, really try to get out on the road. Even if it's just for an hour or two - a two hour ride in late Feb, and another in the first week of March will get you through the race.

Good luck
