Ok so I am in need of weight loss and I have been working on it for some time now. In Jan of 04 I was up around 250 lbs and now I am down to 225 (5'10" and my goal is 170-180 lbs). I was as low as 219 but the cold winter put a few pounds on me as I didn't exercise as much as I needed to. So anyway I commute to work every day which is only 7.2 miles round trip..I assume there isn't much benefit there but also figure that 30 min a day is better than driving for me and for the environment and for my wallet. I also do longer rides but I was reading in another thread about "empty miles". Well there wasn't any real reading just a comment someone made so I want to know if I am doing it wrong or if I should just keep riding.
So lets look at my Sat ride: 40.13 miles which took me 2 hrs 35 min with an avg heart rate of 143. I took one short rest stop where the HRM was still logging so that brought the avg HR down a bit. During this ride I ate one Powerbar and drank 2 large bottles of water and one large bottle of Accelerade. My Polar HRM said I burned ~2400 Kcal (how is that different from cal?).
In my mind this ride is great for me and will help me to loose weight but this comment about "empty miles" makes me worry that I am not doing it right.
What is the real story here? Was that ride a big waste of time in regards to weight loss or was it great for getting me to my weight goal?
Thanks for any input.
