Windsor won his age group at the Mooloolaba Triathlon on Sunday and in the process booked a spot at the Triathlon World Championships in Rotterdam, to be held in August.

The Bathurst triathlete overcame a niggling achilles injury on Sunday to win the 55-59 years age group.

Windsor completed the Olympic distance of a 1.5 kilometre swim, 40km ride and 10km run in a time of two hours, 10 minutes and 43 seconds.

That time put Windsor exactly three and a half minutes clear of the nearest rival in his age group, Brian Elvery, with another 16 seconds back to Malcolm Miller.

Windsor said the nerves kicked in during the lead up to the race.

“I was a little anxious leading up to the race because carrying this injury in is something I haven’t had to think about before,” he said.

“I made this race a goal for the year. I really wanted to defend my title and I ended up putting a bit of pressure on myself, which is not normally something that I would do.”

However, thanks to a strong performance across all three legs – including a stellar job on the bike – Windsor need not have worried.

Windsor emerged from the water 15th in his category but, unsurprisingly, made his ground back with pedal power.

Not only did Windsor finish fastest in his category on the bike but his time of 58:11 was strong enough for 10th overall.

Windsor was sixth in his age group for the run but had built up a big enough lead to stay clear of his competition.

“It’s not my sort of course for the bike. I would have liked a few more hills, to be honest. It’s so fast riding on the motorway and back … so I couldn’t be happier with how I went on that,” Windsor said.

“The guys back in second and third, I didn’t know how far ahead of them I was after the bike so I started a little stressed on the first half of the run.

“It was so hot too. It’s a struggle for someone from Bathurst to come up to Mooloolaba and run.”

Windsor said a venture to Rotterdam for the World Championships will be dependant on how he pulls up over the coming weeks.

The result comes after Windsor managed a third place finish third in the Central West Inter-club Series.
