Ben Bullock and Richard Ditchfield will complete the 126 miles from the Black Country to West London by doing laps of the Grove pitch.
The pair began the challenge yesterday with the plan of walking 18 miles - which equates to 72 laps - each day until Sunday.
Funds raised will go towards providing new changing rooms and dugouts for the Yeltz, who stood one step from Wembley in the semi-finals of the FA Trophy when the season was halted by the coronavirus.
The duo will be joined each day by a different members of the Halesowen first-team squad, while their effort is being filmed by Yeltz TV’s Matt Ponter.
Bullock explained: “The final of the FA Trophy was due to take place last weekend and we had hoped to be there.
“Richard, my stepdad, had the idea of walking the distance there and when we got in touch with the club they were happy to let us use the ground.”
