Two-time Olympian Jeff Riseley was forced to withdraw from the 800m semi-finals on day two of action at IAAF World Championships, Beijing 2015.

Battling acute soreness to his plantar facia, the 800m Australian champion decided to focus solely on his preparation for Rio 2016.

“This isn’t the result that I wanted but it’s the best decision to ensure my preparation for Rio. I worked hard with the Athletics Australia medical team and my coach to give myself the best possible chance for a start in the semi-final, but during my warm up I could not do what I needed to do to run well. I don’t want to compete at a level any less than what I know I am capable of. It’s disappointing, but in my best interest long term,” Riseley said.

On the opening day of competition Riseley finished strongly to automatically progress from 800m heat five of six in a time of 1:46.79, before succumbing to injury.

“I came here in amazing shape and think I showed that in the heat. The plan now is to recover and make sure that I take a similar level of preparation to the Olympic Games. I know I am able to run well against the best at a major championship and plan on doing that through more than the first round next year.”

Knox middle distance runner Melissa Duncan finished tenth in heat one of the 1500m with a time of 4:09.29 to just miss out on progressing to the semi-finals.

“So grateful and proud to be able to have such a quick comeback from a stressie to represent Australia at the World Champs and, only just miss out on a spot in the semi,” Duncan Instagramed.

“I couldn’t have come back so seamlessly without the huge support from Run Canberra and Athletics Australia, couldn’t be more grateful for your belief in me. So excited for the year ahead.”

Using the 20km event as preparation for the his more fancied 50km Jared Tallent was the best of the Victorian’s finishing 26th in 1:24.19 while fellow Big V walker Chris Erickson finished 32nd with a time of 1:25.15.
