British hurdler Lawrence Clarke says he is confident of hitting his peak to coincide with next year's Rio Olympics.
Clarke, 25, has endured a frustrating time since finishing a surprise fourth in the 110m hurdles at London 2012.
A broken wrist and pulled hamstrings ruined 2013 and he had to withdraw from the European Championships final after tweaking his hamstring in the warm-up.
"Statistically, the peak age is 26 and I'll be 26 next year," Bath-based Clarke told BBC Points West.
"I'm rounding into great shape, I'm back to where I was in 2012 and really the next 12 months will be capitalising on the consistency I've had and trying to get a bit faster to get into that medal zone."

With a year to go until the Rio Games, Clarke says he is relishing the event in South America.
And he believes he is well placed to better his performance in London three years ago.
"It's the one thing I've been looking forward to for the past four years, well really all of my career," he added.
"I had a string of debilitating injuries which took the edge off things. I was 22 in London and never really expected to make it past the semi-final and to make the final and come fourth was a real surprise.
"Now the people who are the best in the world are all my age and I've been racing them since the beginning so I know my competition and know when and how to put them under pressure. It's an open field next year.
"A lot of the older guys like David Oliver, the reigning world champion, is 34 and Will Sharman, who is arguably the best British athlete of the past few years, is 33 next year so there is a new generation of people coming through who are 25/26.
"The door is opening, I just need to muscle my way in, put the hard training in and hopefully I can get there."
