The most step ups in eight hours is 8,898 step ups and was achieved by Arran McLellan (Canada), at the University of Victoria Stadium, Victoria, British Columbia, Canada, on 4 June 2011.
Arran’s dedication in setting the record led to him having to stop the attempt after less than six and a half hours due to him sustaining a hip flexor injury and heat stroke. However, he was still able to set the record in that time.
