Nachshen, who is 14 and attends Immanuel College, cut his personal best by more than a second to record 1:59.10 in the latest Watford Open Graded Meeting.

“I was placed in a field of older athletes who were aiming for 1:55, and I was knocked around a lot during the race,” remarked Nachshen (left). “I passed half-way in 59 seconds, two seconds slower than I had planned. But I maintained my pace and made a final push in the home straight.”

Nachshen trains twice a week at Allianz Park, under the guidance of Jeremy Sothcott, in a group that includes several Jewish athletes, including David Stone. His programme also includes a Sunday morning session at Parliament Hill.

Nachshen said: “My training at Shaftesbury Barnet has been going really well recently, with a lot of sprint repetition work with short recovery periods.”

He will spend two weeks in Israel on a school trip before representing Hertfordshire at the England Schools Athletics Championships in Birmingham next month.
