This is a little utility to compute arbitrary splits from a tcx file. This is common problem - you have the splits from auto-lapping or manual laps, but you're also interested in the splits for some other distances. Or maybe you do not have any laps, but want to know some splits. Just upload the tcx file and the requested interval (in metres) and the splits will be calculated for you.
Disclaimer: This seems to work for me - but don't rely on the results. If you have files for which you get an error or obviously wrong results let me know and I'll see if I can fix it. I don't deliberately keep copies of the tcx files once the splits have been calculated - but maybe I've made an error somewhere so don't rely on this!Paul Rudin
