Holbeach athlete Lloyd Kempson continued his excellent season with two personal bests in the space of five days.
The in-form Nene Valley Harrier broke two minutes for the first time in the 800m at the Watford Open Graded Meeting last Wednesday and then improved his mile time to 4.29 in London on Sunday.
It was his second impressive road mile display in London this year, having won at the Westminster Mile event last month.
The former Spalding Grammar School pupil said: “There were three elite races. The men’s A race was won in 4:04 by Australian Olympian Ryan Gregson and the elite women’s by Genevieve LaCaze, then there was the elite B races that I was in.
“It was won in 4:12 by Jack Hallas and I was fifth in 4:29. It was a very tough course with multiple inclines and a lot of corners so I’m chuffed with the time.
“I was the youngest out of the top five with the rest all being seniors so, all in all, it was a top run.
“I went through 800m with the front group but in the final 600m my legs just fell off and I struggled towards the end.
“But I gave it a go to try and get a top three position and I came away with a PB and have taken some scalps so I am very happy.”
Kempson improved from 2:00.5 to 1:56.55 when finishing fourth in his race at Waford, where he was one of two Nene Valley athletes to break two minutes for the first time.
Bradley Spurdens was third in his race in 1:59.19, taking almost three seconds off his previous PB.
Bourne Grammar School pupil James McCrae was the fastest Nene Valley on the night, finishing fourth in his race in 1:56.31 – just over a second outside the English School qualifying mark.
Spalding multi-eventer David Bush was sixth in the heats of the England Under 23 Championships 400m hurdles in 57.54 at Bedford.
