Among the Tauranga locals walking and running the Tauranga Half Marathon this Sunday, will be the pitter patter of paws.
The Tauranga Half Marathon has this year partnered with the Tauranga Heart Foundation, a cause close to the heart of a number of local competitors.
Wilson, a 1-year-old jack russell terrier, has entered on behalf of his buddy Aslan, a 4-year-old huntaway, who has had a grade four heart murmur since his birth.
"It's quite serious, he can't go for a run or on the beach," said Wilson's owner Matt Macmillan.
Mr Macmillan said Wilson was the fundraising mascot, and would be "doing it for Aslan".
