A man that did 401 marathons in as many days - the equivalent of the distance between Stonehaven and Syndey - talked to the pupils at Arduthie School about his challenge.
Ben Smith spoke to around 20 pupils from the Stonehaven school, who then joined him on the first mile on what was his 281st day of running.
The new Stonehaven Half Marathon was completed in the morning, followed by lunch at Number 44 before moving on to finish the second half in the afternoon.
Ben took on the challenge with the aim of raising £250,000 for two charities: Stonewall and Kidscape.
The two charities promote equality for the LGBT community and support bullying victims respectively.
