Paula Radcliffe fears for running career after injury complications

Paula Radcliffe reveals she is currently unable to run and fears that continuing her career "may not be possible" following a long-standing injury.

Radcliffe tells BBC Sport's Frank Keogh how she has even struggled "to run after the kids" but says she would "love to be able to run a couple more marathons" if her foot heals enough to allow her to do so.

The marathon world record holder has suffered with osteoarthritis throughout her career, and has not been able to run beyond a short jog for eight months.
