Philip Goodeve-Docker and his team mate Andy Norman were both "rookies to the Arctic" according to Mr Norman.
Writing on his website before the trip, the 33-year-old former IT professional said he was "setting foot for the first time in the Arctic Circle" and described Mr Goodeve-Docker as "completely new to the Arctic and indeed this adventure lark" but added that his friend had been "training furiously".
Mr Norman and Mr Goodeve-Docker undertook the unsupported crossing with experienced expedition leader Roan Hackney.
The trio was supported and monitored during the trip from the UK, managed by a world leader in managing Greenland expeditions.
Mr Norman and Mr Hackney remain in hospital.
