On the eve of her first return to the stadium where she won heptathlon gold, Sheffield's Jessica Ennis-Hill has spoken of her fears about losing all her outdoor training facilities in her home city.
Don Valley Stadium will close in September and Jess says she's not confident that its replacement will be ready in time for her winter training regime.
