I was also not a runner until about 1 year ago, if you asked me 2 years ago I would have said I hated running and only did it when I traveled and there was not other option. Last summer I started to run more regularly mostly to cross-train for biking. When I started I couldn't run 2 miles straight and now I can do over 5 and have taken over a minute off my mile pace, as others mentioned the key is to start slow, intervals are great for building up the endurance. Swimming is my real challenge...

I have seen some aqua-bikes listed in MA. They are usually part of Olympic distance or longer tris. check out www.trifind.com/ma
