Socks have been hidden at various outdoor locations across the city and Sport Relief is challenging the people of Milton Keynes to track them down, take a photograph and send it in to BBC Three Counties website at threecounties@bbc.co.uk

A selection of the best photographs will be displayed on the Three Counties website www.bbc.co.uk/threecounties over the coming weeks.

The limited edition socks are a must have for the Sainsbury’s Sport Relief Mile which comes to Milton Keynes on Sunday 21st March. The Milton Keynes Mile starts in the heart of the city on Midsummer Boulevard and promises to be a jam packed day of fun entertainment for all the family. With 1, 3 or 6 mile distances to choose from, there is a challenge for everyone, from the super sporty to those who just want to have fun.

The Milton Keynes Mile is the perfect way to get involved with Sport Relief, have fun and raise cash which will help transform the lives of those in desperate need across the UK and in the world's poorest countries. To enter visit www.sportrelief.com.  
Sport Relief socks are available from Sainsbury’s priced at £2 a pair with at least £1 going to Sport Relief.  Available in a range of sizes for adults and kids, they contain Fairtrade Certified Cotton ensuring small scale cotton farmers in developing countries receive a better deal from trade and can improve their livelihoods.
