There are 3 basic options:
- Spin Classes
- Indoor Trainer
- Ride Outside

Assuming you actually get on the trainer and complete the workout it is the best option. You are on your bike which means you are working the muscles in the precise position they will be in on race day. You're also practicing staying in the aero position. If you're racing Half Iron or longer I recommend wearing your helmet for long rides on the trainer. Yes, you look like a dork but you've got to get your neck muscles used to the added weight or you will really suffer on your first outdoor long rides.
I typically recommend a mix of trainer rides and spin classes. While most spin classes are less than ideal, the social interaction and thumping music break up the monotony of riding the trainer on your own.
