On the run and behind bars: Justice Secretary wants more prison exercise

Every Saturday more than 800 locations across the country play host to parkruns - involving hundreds of thousands of people prepared to jog five kilometres around their local park, whatever the weather.

But in one corner of Northamptonshire - in common with twenty other sites across England and Wales - the runners are watched over not just by volunteers, but by guards and dogs.

Our Communities Editor Darshna Soni joined the inmates participating in a parkrun at His Majesty's Pleasure.
