The “Run for all” series inspired by English athlete Jane Tomlinson, who raised £1.85 million for charity by completing a series of athletic challenges, breaks new ground tomorrow morning with the Sheffield 10k.
This is the latest addition to the popular and rapidly-expanding series.
Thousands of runners of all abilities will line up at Arundel Gate for the 9:30am start.
From Arundel Gate the course goes along Charter Row and Ecclesall Road before skirting Endcliffe Park.
It continues along Riverdale Road, Endcliffe Vale Road, down Brocco Bank to a grand finish in the city centre .
The leading runners are expected to finish just after 10am.
Meanwhile, the second South Yorkshire Cross Country League fixture is also tomorrow, at Kiveton Community Woodlands.
This is a new venue for the league and is the site of the old Kiverton Park/Wales Colliery, now landscaped.
It should provide a much more challenging course than the city parks usually used for this event.
The opening meeting provided some keen competition, with Jonathon Shields (City of Sheffield and Dearne) and Samantha Johnson (Rotherham) winning the senior races.
