He believes a reunion with Worcester Athletic Club coach Deirdre Elmhirst, following a spell working with Olympic silver medalist Robbie Grabarz, is also bearing fruit.
“I think we just clicked,” he added. “Everything we knew about each other before, the chemistry, is working very well.
“We’re both on the rise together and it’s a really nice feeling.
“We had targets of about 2.25 of the Commonwealth (Games) standard, but as soon as I went out there I knew all I wanted to do was win. As soon as I finished the job, I was absolutely happy with it.”
Clarke-Khan, who is engaged to British pole vaulter Molly Caudery, now has his sights set on selection for this summer’s Commonwealth Games in Glasgow.
Another goal is to compete again in Birmingham at the European Championships in August, but the rejuvenated athlete knows he will have to jump even higher to earn the right.
“I know there’s a guy in America representing the UK and he looks great too, so it won’t be an easy job, but I’ll keep working and doing the best I can,” he said.
“The start to the season has been fantastic and if we can continue to build, I hope to be in a position to be selected for those championships.”
