If you've got an hour a night and one ride of two to three hours at the weekend, you shouldn't have any problems completing the Manchester to Blackpool.
All depends on your goal, do you want to tank it in under three hours, or just enjoy the ride?
Pretty well my thoughts too.
However, some more structured advice.
Set a baseline:
Measure your resting heart rate every morning. As you get fitter, you'll see it come down. Also, if it is over 10% above average one morning, that's a signal to take it easy for a couple of days - you're either overtraining, or getting sick with something. HR monitors can be very useful tools.
Identify a ten mile circuit, and do it once a week. Your time will come down, and you'll be able to measure how much faster you're getting.
Structure your training:
Don't try and do the turbo every night. Unless you have an iron will, you'll go crazy with boredom. You'll also get tired and at risk of over training. 3x a week is plenty. Remember the muscles get stronger when they are resting. Mix the training up - do intervals - if you're watching telly, sprint for the ads interval, push hard for the song you're listening to, that sort of thing. This will help you to stay interested, and also help to train your body for real-life cycling.
On non-turbo days, do some strength exercises - press-ups, sit-ups, pull-ups (or half-pull-ups, or let-downs, or whatever you can manage), back raises, lunges, step-ups. These will all strengthen your torso and trunk, often neglected in cyclists. They can all be done in front of the telly.
Build training and weightloss into everything:
Get off the bus earlier and onto it later. Take the stairs, not the lift. Carry the shopping round the supermarket in a basket, not a trolley. Walk to see a colleague, don't send an email. Eat fruit instead of chocolate. If you must eat chocolate, make it 75% cocoa solids - you won't need much. Drink diluted fruit juice instead of coke (by the way, you can make your own isotonic sports drink with 50:50 juice:water and a pinch of salt). Have a low-fat plain yoghurt instead of biscuits. I lost 6-7 kg with the GI diet earlier this year without suffering.
Enjoy yourself, it sounds like you're going to have some fun, make some changes and really have a good time. Let us know how you get on.
