Brownlee still struggling after injury

World triathlon champion Alistair Brownlee's preparation for the Olympics has suffered as he recovers from an Achilles tendon injury.

Brownlee may be forced to write off this year's first three World Triathlon Series races as he continues his comeback from an Achilles tear.

The 23-year old tells BBC Sport's Ollie Williams that his recovery is going well but he is still unable to run at full intensity.
