The two athletes have been locked in constant competition throughout their careers and Weir is relishing facing off against the Swiss again on Sunday (May 24).

“It’s always interesting to race against Marcel and it is a bit of fun,” Weir told insidethegames.

“I think there is some added pressure to go under three minutes as everyone is talking about it but it will be tough as it is virtually a straight sprint.

“The conditions need to be perfect but we both have a great chance of doing it.”

The Briton also claims he will retire after the 2017 International Paralympic Committee (IPC) Athletics World Championships on home soil.

"My body is a bit battered and I'd like to spend more time with my young family," he said.

"I couldn't retire after Rio with a home World Championships the next year."

Weir was speaking ahead of what he calls a “busy programme” of upcoming events, including the IPC Athletics Grand Prix in Nottwil, Switzerland, from May 29 to 31.

The 36-year-old will once again return to the scene of his London 2012 triumph, where he won four golds, in July for the Sainsbury’s Anniversary Games, which will include the IPC Athletics Grand Prix Final and coincides with National Paralympic Day on July 26.

Despite failing to claim a record seventh London Marathon title last month, where he lost out to American Joshua George in a thrilling final sprint, Weir does not feel under any extra scrutiny to do well over the course of the summer, adding that he can’t wait to compete at the Olympic Stadium.

“I don’t feel any added pressure because of the Marathon,” he said.

“I had a problem with my glove and that didn’t help and I just didn’t have enough left in the last 800 metres or so.

“It is a bit annoying when people keep going on about the record but I think it will come as I am born to win.

“It’s always special to compete back in London and it will be great to race here again as this feels like home for me.”

It is also set to be a hugely hectic summer for Paralympic swimmers with the IPC Swimming World Championships due to place in Glasgow from July 13 to 19.

British Paralympic champion Ollie Hynd, who topped the podium in the SM8 200 metres individual medley event at London 2012, is hoping for a similar atmosphere to that of last year's Commonwealth Games at the Tollcross International Swimming Centre.

“I’m hugely excited about the Worlds this year as I have titles to try and defend,” the 20-year-old double world champion said.

“I want to put out a benchmark for the rest of the competition ahead of Rio 2016 and I hope that the crowds will get up for it as we often feed of their excitement.

“There’s a lot of depth in my classification so it is going to be tough but I’m looking forward to it.”
