I Am Camelot delivered a career-best effort to score an impressive harness racing win in a C4-C5 event over 2200 metres at the Luxbet Racing Centre in Launceston last night.

The Deborah Williams-trained gelding earned a reputation as a horse that only does his best when he leads but last night the six-year-old was able to settle back in the field from his outside second-row draw and rattle home to score an emphatic win.

It was the gelding's fifth win from 10 starts this season and Gareth Rattray's fourth aboard the son of Safari from five drives.

"The horse was travelling great on the back of the favourite No Spring Secrets and I was happy for that horse to take us into the race but he wasn't going well enough so we had to go six-wide on the home turn," Rattray said.

"He's a horse that gets revved up and hard to handle but he settled tonight and he really finished the race off well."

I Am Camelot is only lightly raced as he's only had 22 starts for five wins and as many minor placings for closing in on $30,000 in prizemoney.
