Doug,
I used to ride a Turbo Trainer back in the early 1980s to early 1990s when I was very heavily involved in track racing, which also included a lot of road riding to build up the miles. Even when it was pouring with rain, if I had a five hour road session planned I still did it, but there were times I used my Turbo Trainer at home.
I used rollers too, but these didn't give a good solid workout, although they were fun to ride and good for a warm up or warm down, but not for hard core physical training.
Most of the time I used my Turbo Trainer (or wind trainer) I did 60 minutes, although now and again I'd go over that.
I would get bored too if I just sat on it and pedaled away for 60 minutes non stop, so I added differing levels and efforts to
keep the boredom at bay.
I did several things: first of all set up in front of your TV and get ready to playback a favourite pre recorded TV Show. Back in the 1980s it
would often be Magnum PI - I remember one weekend with very bad weather I rode the wind trainer for three episodes back to back!
(Other times it would be The Bill - UK and NZ readers will recognise this.)
Sometimes I'd get straight into it - fairly easy at the start, one minute on 53 x 18, then one minute on 53 x 17, all the way
to the 53 x 13 etc, then back up again to the 53 x 14, then 15 etc at one minute intervals.
Other options include warming up then something like a 53 x 17 or 16 then 100% for 12 seconds, then one minute rest, then another 12 second burst etc, but each time dropping into the next hardest gear, working my way down to 53 x 13.
Or 53 x 13 for one minute, hard for one minute, then 53 x 18 easy for one minute, then x 13 for one minute etc.
Or do a 2 or 3 minute Time Trial through each of the add breaks (so don't fast forward through them!) Make it a hard effort though so you're gasping by the end of the add break and chill until the next add break - but not too easy.
Or if you really want to ramp it up, my all time hardest efforts (both on the velodrome, the road, or wind trainer) is do 100% efforts over 30 seconds then ride gently for 10 minutes - 5 or 6 of these over your one hour will be more than enough! If a 10 minute break between efforts seems too much, then you haven't done your 30 second effort hard enough I'm afraid!
Hope some of the above may be of help - these are efforts I used to do myself, so I'm not suggesting anything I haven't subjected myself to.
Regards
