Wow! I was just forwarded info on this event the Pennine Duathlon. It looks amazing it combines my two favorite sports trail running and XC mountain biking in a long course format. I have never seen a race like this in North America, if there is one please let me know about. Maybe next year I will make a trip across the pond for this.
26.2 mile trail run, 100 mile mountain bike, 26.2 mile trail run, combined with the self sufficient format, will test even regular Ironman distance competitors. The Pennines provide their own challenges too. The Long climbs and descents total over 13,000 metres on trails ranging from wide open farm tracks to technical single track.
