Some might have given up on Lenamore. Powell talks of him being "difficult" and a "tearaway" in his youth, being a bit "quirky" and a "bad traveller" but the pair have found a happy working relationship over the last eight years and could figure in London.
Team-mates Mark Todd and Andrew Nicholson, who are both going to their seventh Olympics, might receive all of the attention and be among the favourites but Powell is a chance and will certainly be relied on in the team's event.
She finished 14th in Beijing, the highest-placed rider in the three-day event, and won Burghley in 2010 on Lenamore.
"I'm very quietly confident. He's in cracking form. As long as his brain space is good."
Great Britain and Germany will start as favourites in the team's event at the Greenwich Park venue, built around the prime meridian line and overlooking the city.
But the talk around the stables is about how New Zealand are once again a force. Todd says they have "one of the strongest teams we've ever had" and "you need a bit of luck on your side."
Powell probably feels she's due a bit of that to make up for the tough year.
