Burn it off this week in exercise: enough Calories to lose a pound. That's our Biggest Loser challenge this week.
My Garmin gives me generous caloric expenditure estimates (since it incorporates body weight, I believe), so that's what I'll use. Let's check some recent estimates:
Last Sunday, run 10.24 miles, burn 1287 Calories. That's 125.6 Calories/mile, or it would take me 27.8 miles running to burn off a pound. I think that's a reasonable estimate. Right now I do that approximately every two weeks.
Today, bike 33.03 miles, burn 2254 Calories. That's 68.2 Calories per mile, or it would take me 51.3 miles cycling to burn off a pound.
3 hours 25 minutes easy-pace cycling (15 mph) versus 5 hours 33 minutes easy-pace running (12 min/mile)? Heck, I'll take the cycling any old day. Bring it on. (Except I don't really think that estimate is accurate for cycling, but who am I to argue with the Garmin experts!???)
Hmm, we get more points if we burn 7000 calories. 102.6 miles in a week? I could do that, except it's been a while since I've actually done it, but it's much easier to double (or even triple, with my low cycling mileage lately) your cycling distance in a week than double your running distance.
We'll see. First I have to get serious about getting rid of my nasty hacking cough.
