The whole HR debate does get a bit complicated sometimes. I guess my main frustration is that when I go on organised training rides I keep (eventually) getting dropped when I get to the 180 mark, the same time that the pace steps up a notch higher. When I asked a couple of the riders in the bunch what their heart rate was the responses were varied. For example one guy was only at 155 when I was beating at 180, however another girl was at 187 when I was at 180. The problem is that they are not getting dropped, they can keep up, where as I am left to complete the ride on my own.

So I wonder is it my heart and lungs or my legs that are the problem, or both??? Am I ever going to be able to keep up??? Maybe I need to work on my leg strength?? Any ideas would be welcome.
