Shanaze Reade tempted by track cycling at Rio 2016

Great Britain's BMX star Shanaze Reade says she is interested in changing disciplines and returning to track cycling, with the hope of replacing the retired Victoria Pendleton at the 2016 Olympic Games in Brazil.

Reade failed in her bid to win gold in the women's BMX at London 2012, coming sixth in the final.

The 23-year-old has competed in two Olympics so far.
