Britain's Jo Pavey has qualified for the World Championships after battling adverse conditions to beat the 10,000 metres qualifying time in Watford.
Pavey was 13.06 seconds under the required time
Pavey lapped every other competitor in the BMC Nike Grand Prix to finish in a lifetime best 31 minutes 26.94 seconds.
On a sodden track, Pavey bettered her previous record of 32:21 and was 13.06 seconds under the required time.
"The weather was horrible all the time but the crowd and the pacemakers were absolutely brilliant," she said.
"Now I've got to prepare for the other extreme and sort out how to run in too-hot weather."
Pavey will begin her preparations by racing the 3,000m at the Norwich Union British Grand Prix in Sheffield on 15 July and will then head for the IAAF Golden League meetings.
Phil Nicholls, who made his GB debut at last winter's World Cross Country Championships in the 35-degree heat of Kenya, claimed his first national track title, winning the men's 10,000m in a lifetime best of 28 minutes 40 seconds.
