Pc Claire Bond, who works for Staffordshire Police, had her life turned upside down when she was run over in September 2018 while on duty.
She was crushed against a fence, broke both of her legs, and then was run over as she tried to stop a disqualified driver from driving into runners at the Stafford 10K.
Now – after taking on a new role in the training department of the force – she has taken on a 10-day fundraising challenge in aid of Mind, starting on September 13.
It has seen her walk 1km a day around the county, with people who have "influenced, shaped and pretty much dragged me through these last two years".
Pc Bond passed through the Birches Valley Forest Centre in Rugeley, where she was joined by High Sheriff of Staffordshire Charles Bagot Jewitt.
Her final walk, on September 23, will be the last 1km she completed last year in the Stafford 10K.
Pc Bond has already raised £1,300 against her original target of £1,000.
And she chose Mind – a mental health charity – to receive the cash boost amid the "unprecedented" impact of coronavirus on people's lives.
She said on her fundraising page "I worry about our mental health, our children who have missed school, or who have been left distraught over their exams.
"All who have no job to return to or businesses to continue building, those whose anxieties have gone through the roof and those who have become secluded – and have no one to turn to, and those who have lost their lives, leaving behind families with immense grief.
"Together we can raise some money and, in particular, awareness that could make that difference to someone we know or a complete stranger just by giving."
