A former European medal-winning athelete has raised more than £1,000 for charity after completing a double challenge.
The first challenge for Matthew Peleszok, 30, was to finish the London Marathon, his fifth, in four hours and 40 minutes.
Then, starting at midnight on Friday, the Kettering resident walked for 20 hours and 12 minutes around Kettering Athletics Track in Thurston Drive. Walking alongside members of Kettering Town Harriers, Mr Peleszok walked more than 60 miles.
Mr Peleszok works at schools in Corby, Oundle and Thrapston as a schools sports manager.
In 1996 he won silver in the 400 metres running at Coupe De Jean Humbert in France.
Money raised will go to Cancer Research UK and the Ken Pickering Memorial Trust.
