Thanks for all the replies.
Just to answer a few questions, yep I'm overweight, I'm 5' 10" and I weigh 14st 3lbs. I know that's pretty bad but I used to be over 16st. I lost it because of a change in diet, cut out all the sugary treats and the soft drinks, I also started cycling, but can't do that at the moment (house fire and bike was damaged).
I did used to swim about a year ago, but I can't do it anymore, physically I'm fine, I just can't stand the other people in the pool.
I don't have any running shoes at the moment, just using an old pair of trainers, but I was thikning of going to a running shop and seeing what they do.
I have kind of been mulling over the idea of joining a local gym.

The problem is unless you do a lot if cycling you simply won't be able to do effective intervals on a bike. I certainly can't do intervals on a bike yet, it will take a lot more saddle time before I have the strength and ability to do that. I hope to be able to one day. To put it in perpective, last week I tried to do a hard session with my trainer on zwift. I cycled so hard I felt faint, bUT I never got my heart rate above 162, which is far lower than 95% HRR desired for effective intervals. In contrast in my 800m repeats when running u had to slow down to keep my HRR below 100%. Much more training required with the bike before it's effective.
