Harry Hughes has warmed up for this weekend’s Sainsbury’s School Games with another potentially record-breaking performance.

Stowmarket-based Hughes, the UK’s No. 1 javelin thrower in the under-17 age group, left senior athletes gob-smacked by another enormous throw at the annual end-of-season Eastern AA’s Inter-Counties meeting, held at Sandy in Bedfordshire last Saturday.

Throwing the senior javelin for the first time, in a competition, the impressive Hughes registered a best effort of 62.30 metres, which is believed to be the longest ever throw recorded by a 15-year-old Briton with the 800 grams javelin.

Competing for Suffolk, against such counties as Bedfordshire, Norfolk, Essex, Hertfordshire and Cambridgeshire, Hughes added another win to an already spectacular season, which has seen him crowned English Schools champion, and also record the second longest throw of all-time (in Great Britain) with the under-17 javelin, weighing 700 grams.

Hughes confirmed: “We think Sunday’s throw was the longest by a 15-year-old Briton, with an adult javelin, but we are just having it checked out.

“That’s the first time I have thrown this javelin in competition.

“Now I’m looking forward to the School Games this weekend. There’s a chance I could break the British (under-17) record, but I think it’s more likely I will achieve that next season, because I still have another year in this age group.

“It’s been a great season for me, and I would just like to put in a good performance at Sheffield.

“Then I will have three weeks off training, to rest up, before looking ahead to next season,” added Hughes.

A member of West Suffolk AC, Hughes travelled up to Sheffield yesterday, ahead of making his debut at the Sainsbury’s School Games on Sunday.

He celebrated a personal best of 72.77m at an Eastern Young Athletes League meeting in Cambridge last month, which propelled him to second on the all-time British under-17 list, and his next target will be to eclipse the long-standing record of David Parker, who set an under-17 best of 73.56 in 1996.

Hughes, who is coached by Mick McNeill, won the English Schools crown at Birmingham in July, just as he had done in the under-15 age group at Gateshead the previous year.

He finally turns 16 on September 26.
