Heather Lewis wore her Pembrokeshire Harriers vest with pride on Sunday was she was crowned British Indoor Champion in the 5000m walk.

The 25-year-old from Clerkenhill Farm held off Welsh teammate Bethan Davies to set a new personal best time of 22:55.

And yet it was Davies who led in the early stages as she forged a lead over Lewis, but then the latter then came back strong and was within 10 metres when Davies was then disqualified from the race.

With her main rival gone, Lewis’s chief challenge was to concentrate on her technique and ensure she didn’t join the growing list of disqualified athletes - and she did just that.

“It’s always very tough technically to race on an indoor track but I’m really pleased to come away with a win - and was very proud to wear my Pembrokeshire Harrier vest,” she told Telegraph Sport.

“My next competition is in Switzerland in Lugano.

“Our usual race walking distance is 20km and that is the start of the season which will hopefully allow me to qualify for the World Championships and the European Race Walking Championships.”
