Six-time Paralympic champion David Weir is happy with his condition as the Rio Games in September approach.
The 36-year-old from Wallington, Surrey won the Westminster Mile for a fourth straight time last week, becoming the first wheelchair racer to race the distance in under three minutes in the process, clocking two minutes 57 seconds.

"It was great to do it," said Weir, who won four Paralympic gold medals at London 2012.
"When the London Marathon and Westminster Mile approached me and said 'it'd be great if you could do a really quick mile'. I said 'no-one has ever gone under three minutes'.
"It's taken three years. The course isn't that great, because it's got bends. On a straight road it would be a lot quicker.
"This year I knew it was going to be done. I just had that confidence.
"I'd been training really well leading up to it and it all went to plan on the day.
"Training's going well. Every training session is improving.
"It's great for me to go into the Europeans next week and show that I can race."
The IPC Athletics European Championships take place in Grosseto, Italy from June 10 to 16.
Then Weir will turn his focus to Rio.
He won gold at 800metres, 1500m, 5,000m and the marathon at London 2012, but is still undecided what his race schedule will be for Rio.
Weir intends to continue on the track until the IPC Athletics World Championships in London next year.
"I'll still go to London 2017 and race on the track there," Weir added.
"Then I'll probably retire from the track and still race on the road, doing the marathon circuit.
"That would give me a bit more time off in the summer to spend with the family."
