Millwall's Performance Coach Dave Carolan is running 5K every day in November in aid of Prostate Cancer UK.
Carolan, a vital member of Gary Rowett's backroom staff at The Den, has pounded the streets in getting his incredible task underway - and he is looking for Lions fans' help in sponsoring him and donating to the charity.
One in eight men will be diagnosed with prostate cancer in their lifetime. That's a dad, grandad, brother, partner or friend. To help stop this deadly disease, Dave is taking his challenge on to raise money to fund life-saving research.
