2022 marks the 15th Newton’s Fraction Half Marathon run under UKA rules, on an accurately measured 13.1 mile route. The race is one of the county’s most popular road races. Organised by Grantham Athletic Club, the race starts and finishes on the track inside the South Kesteven Sports Stadium, Trent Road, Grantham.

The course heads out of town into the countryside onto the Grantham to Nottingham Canal towpath for nearly 3 miles to Woolsthorpe-by-Belvoir, taking in a couple of testing hills , before returning to the stadium for a grandstand finish.

We have plenty of on-site parking, refreshments, a Lincolnshire Runner stall, bar and each finisher gets a t-shirt, medal.

“Brilliant course. Well supported and beautiful countryside. A couple of challenging hills too.” – Alessandro Ferrari, 2019
