I hated running, too. Until I started the C25K-programme, which I am currently on - and realized the reason I hated running was that I was pushing myself too hard for someone unfit! I used to go running with friends who excercise a lot etc., and tried to keep up with them - it wrecked me and I didn't understand how anyone could like running. Now I have been running 3 times last week and also went running today and I love it so far! The programme starts off easy and let you do things at your own pace, you can also repeat a day if it's too tough for you. Having a programme, that counts minutes etc. for you, is much more motivating than just going out there to run.

I think it's a good idea to just try different stuff. Personally I am now in a phase where I want to try everything - roller derby, kickboxing, swimming etc. - to find something I like. My problem with swimming is that I honestly find it a bit boring. With running at least you can be outside and you can listen to music and so forth. But swimming is great in the way that you can swim a really long distance without even realizing it just swimming back and forth, it's a bit like cross-country skiing in that you don't really feel exhausted or tired at all until you finish.
