A charity has two free places for the Cambridge half-marathon up for grabs.
The AKU Society funds medical research to develop a drug for a rare genetic condition called Alkaptonuria (AKU).
The condition is caused by a build up of acid in the body which attacks bones, cartilage and tissue, leading to severe early-onset osteoarthritis and heart disease.
The charity is offering the two half-marathon places in return for fundraising.
Runners will be dashing around Cambridge on February 28.
