Commonwealth champion Alistair Brownlee wants to keep improving as he gears up for the fifth round of the World Triathlon Series in Yokohama, Japan.

The 27-year-old missed the start of the season but made sure he hit the ground running when he made his return to action with victory in Cape Town three weeks ago.

Brother Jonathan will not feature in Saturday’s race but will make a return as the duo go head to head on May 31 in London’s Hyde Park.

There will still be plenty of high-calibre competition for Brownlee to contend with however as world number one Javier Gomez of Spain takes his place in the lineup.

But Brownlee says he is closing in on his finest form and wants to make sure he delivers with a strong performance in Japan.

“I’d like to feel like I’m progressing, and that I’m sharper now than I was three weeks ago in Cape Town,” said Brownlee.

“I missed the first three races, so every race is important now if I want to be in contention at the end of the season.

“Let’s see what Saturday brings, hopefully another good result before Jonny and I race each other in London."
