While his participation in this year’s IPC Athletics World Championships may be up in the air, six-time Paralympic champion David Weir insists he is sure of one thing – he is as fast as ever.

Last year’s Commonwealth Games gold-medal winning performance aside, it has been three years since Sutton’s wheelchair racer Weir competed at a major international championships after opting out of the 2013 Worlds, while injury ruled him out of the 2014 European Championships.

This year’s Worlds in Doha from October 22-31 would offer him the chance to add to his six world titles, although with the New York marathon shortly afterwards on November 1, Weir admits he is torn over whether to compete.

The 35-year-old won silver at last month’s London marathon – which also doubled as the marathon event for the World Championships – despite being hampered by a problem with his gloves.

“It wasn’t my fitness or my mental state – I was in the best shape ever – it was just my equipment which let me down in the London marathon,” said Weir.

“To get silver was a brilliant job for me. Yes, I was a bit disappointed at the end but I’ve just got to move on from that.

“My form is up there at the level that it was in 2012. At this time of the year, I’m probably fitter and faster than I’ve been in previous years.

“I did some time trialling on the track last week and I was shocked to see the times I was doing.

“I’ve not decided about the World Championships yet as it’s quite close to the New York marathon. I would love to go.

“If I can fit one race in and, if it’s possible and do-able, then I will be there.”

Weir will race on home soil at the Sainsbury’s Anniversary Games at London’s Olympic Park on July 26 – with the athletics event also doubling up as part of the celebrations for National Paralympic Day.

Building upon the legacy of London 2012, National Paralympic Day will also feature international para-swimming at the London Aquatics Centre.

And Weir admits the chance to return to the scene of London 2012 is one he is relishing.

“I’m really looking forward to national Paralympic day, I think it’s very important to keep that legacy going from London 2012,” he added.

“I’m glad it’s back in the stadium. I’ve got great memories from racing there in 2012, so I’m looking forward to racing a 1,500m against my biggest rivals around the world.”
