It's insane.  I did a 60 mile bike ride this week that was 2000+ calories.  Bike racing is much less calorically intense than running or swimming.  Guys I know who race triathlons ,besides being terrible pack racers on a bike :) , train all the time.  Like 20+ hours/week.    Now either this fat bitch is training like that and putting Burger King out of business, or she's taking a picture next to a bike and making shit up. ALSO: Nobody does a race on a fucking hybrid bike.  Tri bikes are insanely aerodynamic and are ridden is a ski-tuck position.
