Welcome Scott!! That's some very impressive weight loss so far. Congratulations!
Consider doing one of Lifetime Fitness's Indoor Triathlons this winter or next spring. It's a nice introduction to essentially a sprint distance race, but is run for total time (10 min pool swim, 30 min on spin bike, 20 min treadmill run) as opposed to a set distance. I'm not sure if they have one down in Rochester, but it may be worth the drive up to the Cities if you find one that fits your schedule. You don't have to be a Lifetime member to do it either!
