I am a 40-something mother of 4 who has taken up a challenge from my marathon-running sister. Do a triathalon with her and she will attend a scrapbooking weekend with me. Now I am on the road to train- run, bike, and swim my way back to a not-embarrased-in-a-bathing-suit weight, and enjoying every minute of it.
Well, not every minute.
Note to self--sister is very persuasive. Next time she approaches you with a challenge, run the other way. : )
