I just bought a polar F6 and have been using it when I ride. I am fairly new to training, but have been regularly riding for about 4 months.
Today I rode for an hour and ten minutes (including 5 minute warmup before, 5 minute cool down after). At the end of my ride it told me I burned 1375 calories in the 70 minutes with an average heart rate of 185. Is this way too much or is that possible? It just seems like a whole lot of calories for an hour ride. The area I ride is all flat with maybe 3 slight inclines (15 degrees max) each only about 100 feet so there was really no heavy climbing involved, however it was VERY windy today, and I was going against the wind for probably 70% of the ride. Average speed was 16 mph, and I did a total of about 20 miles.
Like I said, I am new to training, so just trying to see what is normal. If it helps, I am a 24 year old male, 6'1, 175 lbs.
