Between work and family, I'm having trouble fitting in triathlon training. I'm concentrating on running, and I'm above-average on a bike. I've got swimming down. I could manage to spend 2 hours a day on my bike IF I could find some way to read while I do it. Are Cyclops-type trainers a good way to improve my cycling endurance or are they too non-road-like to be worth the money? Any specific brand/type recommendations?
