Great Britain's David Weir has admitted that he set out to prove a point during his victory in the Berlin Marathon over the weekend.
The 36-year-old, who set a new personal best and British record of one hour 27 minutes and 36 seconds in the German capital, said that he wanted to demonstrate how he is still capable of winning a marathon solo.
"I didn't just want to be tactical. I wanted to prove a point that I can still race and do a marathon on my own," Weir told BBC Sport.
"I'm looking forward to next month and New York [marathon]. I've concentrated on the marathons and once I do that I seem to do well on the track as well."
Weir crossed the line ahead of second-placed Swiss Heinz Frei in Berlin as he shaved 41 seconds off his personal best.
