Phew, after much tinkering, the N.P.C.C.I. is finally ready to go. As you can see above, there are a couple of options to click. The first one is the N.P.C.C.I. Calculator. Dump your Strava details in there and it will give you a score. The other option is the N.P.C.C.I. Explanation page. That will give you some idea of what I am trying to achieve with this index.
Thanks for all your patience over the past week or so. I hope you enjoy using it and get some satisfaction out of the numbers you can get from riding the hills.
