He was riding in the cycle lane on Wednesday when a motorist cut across him to turn into a driveway. The rear left hand side of the car smashed into Doe.
"I was pretty dazed when it happened," says Doe. "At least the driver rang me yesterday which was a nice touch, he didn't have to do that."
A win in the Rotorua half ironman three weeks ago had Doe perfectly on track for the Tauranga event yesterday and his main focus - the Ironman at Wanaka in a fortnight. The southern event may be in doubt but Doe is not giving up hope.
"I'm pretty stubborn and determined and I'm sure I'll be there," says Doe, who won Ironman Canada in 2007 and is one of the strongest swimmers in the sport, as well as being extremely quick on the bike leg.
Training partner Terrenzo Bozzone echoes those sentiments: "He was pretty shaken up but he is a tough guy. It is never nice being hit but I would put my money on him making it to Wanaka."
Doe has started his comeback already, completing three hours on the cycling wind trainer yesterday, followed by a 45-minute run.
