Echo all the comments on fans, music etc....
Two tips:
First - I use a heart rate monitor. I always found it really hard to judge the intensity I should be working at - until I got the HRM. Programs available from Polar etc give you 10 mins at 70% then 40 mins at 80% and another 10mins at 70%. Focusing on the HRM level and time left to go at the % helped to pass the time and reduce the boredom....
Second - get some cheap aero clip-on bars....... I'll show you why in a minute
