SWIM Bournemouth’s Drew McGregor trashed the formbook to become a national champion twice over in Sheffield.

The 13-year-old from Wimborne was one of four Dorset swimmers who struck gold six times between them at the Swim England Summer Championships.

McGregor arrived at Ponds Forge ranked seventh and eighth in the 13-14yrs 100m and 200m breaststroke.

But he slashed his PBs to qualify fastest for the finals, then lowered them again to win the 100m by almost a second in 1:10.36 and the 200m by 2.59sec in 2:32.46.

The times would have placed him eighth and fifth in the previous week’s British Summer Championships, contested by the top 24 in the country.

McGregor, who improved his PBs by 3sec and 7.5sec, said: “It’s only since the Dorset Championships in February that I’ve realised I’m a breaststroker. I was hoping to win the 100m but my aim with the 200m was just to make the final.”

Mum Nicola added: “He shocked us with his times. We weren’t expecting it.”

Bournemouth Collegiate School’s Christian Tai (BCS) also struck gold twice, winning the 16yrs 50m and 200m butterfly in 26.39 and 2:11.01 as well as reaching the 100m breaststroke and 400m individual medley finals.

Poole’s Jazz McCrea added to her four medals from the British event with gold in the 200m freestyle in 2:05.82, silver in the 200m breaststroke (2:42.60) and fourth place in the 100m breaststroke (1:15.77).

Swim Bournemouth’s Dorset 1500m freestyle champion Oli Fairman, 14, proved he can cut the distance event at a higher level, winning the 15yrs title in Sheffield by four seconds in 16:58.53.

Poole’s Teagan-Mae Graham added a last-day bronze to the Dorset tally with third place in the 16yrs 800m freestyle (9:25.71).

Clayesmore’s S14 para-swimmer George Kelman-Johns took silver in the multi-classification (MC) 100m breaststroke in 1:18.40.

Fellow para-swimmer Leo McCrea made four MC finals, coming fourth in the 100m freestyle, seventh in the 400m freestyle, eighth in the 50m freestyle and 10th in the 100m breaststroke.

BCS’s Ben Samuel missed a medal by 0.09sec as he came joint fourth in the 16yrs 50m butterfly final (26.86) won by team-mate Tai.

He was also sixth and ninth in the 100m and 200m freestyle.

Swim Bournemouth’s Amy Brown was within 0.57sec of a medal as she came fourth in the 12-13yrs 100m backstroke (1:07.99). She was also 13th in the 200m back.

Other finalists included Poole’s Thea O’Keefe with fourth, sixth and eighth in the 17 and over 800m, 400m and 200m freestyle, Seagulls’ Miles Ward with 10th in the 13-14yrs 1500m freestyle, Swim Bournemouth’s Lucy Pearce with 10th in the 17/o 1500m, and BCS’s Alex Bryant with eighth and ninth in the 15yrs 50m fly and 200m back, Alesha Gibson with fifth in the 16yrs 200m breaststroke and Ella Chown with sixth in the 14yrs 50m freestyle.

Other results: 12-13yrs Alex Palotai-Avella (BCS) 12th 400m freestyle, 13th 800m freestyle. 14yrs Chown 12th 50m backstroke, 18th 200m freestyle. 15yrs Abbie Quarrie (Poole) 11th 200m breaststroke. 16yrs Trevin Michelo (BCS) 16th 200m breaststroke.
