I tried to get a power strategy for a cycling course. I input the bike's weight, but when I went to finish the strategy the bike weight (18.5lb) had replaced my weight. I tried to change this a couple of times but it wouldn't let me keep my own weight. I forgot I'd done this. I went for a run and my calorie expenditure was drastically reduced as the watch (FR965) thought I weighed 18.5lb.
