London Duathlon (Sun 18 Sep 2016) are being clear about their pricing. It normally sells out anyway. So lucky they haven’t hiked the prices too much like the ALCATRAZ OLY aTRI week or so ago. Didn’t go down well.
A quick FYI. The ULTRA distance counts as a qualifier for the BTF/ETU/ITU long distance duathlon events. As would the ‘duathlon component’ of a HIM. Not a lot of people know that.
