That’s 700 miles!
The challenge aims to raise £50,000 for Bright Horizons Foundation for Children and will take 10 days, covering up to 80 miles a day.
The cyclists will be visiting nurseries along the way, stopping off at Tiny Toes on May 15.
The children at Tiny Toes will be taking part in a sponsored cycle on 15 May and nursery manager Rosemary Quint will be cycling to work from her home in Tring to help raise further funds for the foundation.
Tiny Toes uses a grant from the foundation to support a local woman’s refuge, which has a refurbished playroom and holds monthly play sessions for children in the refuge once a month.
