Inverell farmer Glenn Morris and his horse Hombre left Glen Innes on Thursday morning, to urge action on climate change.
Mr Morris is riding for five days down the New England Highway to raise awareness of the issue in the lead up to the federal election.
Both farmer and horse gained national attention in 2016 when they crossed the Sydney Harbour Bridge. This time they are taking a five-day trip from Glen Innes to Uralla.
When the electorate last went to the ballot box, at the 2017 byelection, Mr Morris was one of four farmer who galloped through Uralla to protest the "lack of leadership" on climate change.
"This is an urgent message. We need climate action, we need our leaders to step up and we also need our community to demand more from our leaders," Glenn said before departing.
"I've watched too many elections while I've been researching climate change come and go with no emphasis at all on the environment."
On the first day of riding on Thursday, Mr Morris and Hombre travelled south to Ben Lomond then continued onto Guyra on Friday.
Over the weekend they are heading towards Armidale, and will ride through the city on Sunday morning before continuing onto to Invergowrie.
The final leg of the ride is on Monday, from Invergowrie to Uralla.
