I had been a moderate runner for awhile (never fast, always less than half marathon) but an achilles injury (that appears to be a chronic old man condition) largely ended that. Switched over (or I should say back) to cycling. Outside on nice weekends plus 3-4 times during the week, either at lunchtime or after work. My standard outdoor ride is about 70 miles with some rolling hills (though largely flat), about five hours of pedaling. I'm now starting to acquire gear to ride in cold (but not super cold) weather. I'm not hardcore, but mid-Atlantic is fairly mild compared to other places I've lived so I think (perhaps naively) that there may be some opportunity for outdoor ride before March/April/May. On a spin bike, my typical ride is 75-90 minutes.
That combination, plus some diet changes (less red meat and dairy, salty snacks now just mixed nuts), has lead me to shed about 18 pounds over last 9 months. No longer a little pudgy, and now with a refreshed wardrobe.
