Crypto-currency Dogecoin has extended its deal to sponsor Nascar driver Josh Wise.

Having originally backed Phil Parsons Racing driver Wise's entry in the Nascar Sprint Cup race at Talladega on 4th May, Dogecoin has teamed up with social networking service Reddit to sponsor Wise again.

Dogecoin and Reddit have sold over 5,000 t-shirts designed to mark Dogecoin's initial deal with Wise and will now use the funds raised to back the 31-year-old in the Geico 500 at Talladega on 19th October.

"We're really excited to expand our partnership with Dogecoin and Reddit," team owner Phil Parsons said. "With all of the support we received for the All-Star Race and the number of people asking about apparel, it made sense to have T-shirts produced and turn it into an opportunity to fund a second race."
