The ride, which is held near the Clyde River in Nelligen, is expected to crack 150 riders for the first time this year according to organiser Jenny Shepheard.

"We're looking at about 155 riders at this stage, and we had 140 last year," she said. "We're also expecting a few late entries on the day, so it'll be quite bigger than last year.

"We're currently trying to chase up another vet to accommodate the increased numbers.

"When we started, the 10-kilometre ride only had six riders, but this year we've got 38. It's a very popular ride with locals who want to bring their children to have a go, or adults who want to get in to endurance riding."

The recent dry weather will make the tracks harder under foot, but Shepheard isn't too concerned.

"They're all a little bit harder than normal, but River Road always gets more moisture," she said. "It's very smooth at the moment, and a little bit softer.

"None of the tracks are too rocky. There may be the odd place where they're washed out, but they're all pretty good under foot.

"We've got a few less-used tracks up in the bush as well, so that should be softer ground."

Shepheard said spectators were welcome to come along and watch the action.

"Anyone is welcome to come to the ride base and check it out," she said. "If they want to go to one of the checkpoints, that's OK as well, we just don't want too many cars out on the tracks with the horses.

"The ride base will be the best spot. You can watch the horses come and go, watch them get vetted, and there will be plenty of food."

Shepheard said the ride showed no signs of slowing down, but did say the event was always looking for new volunteers.

"We've got enough for this year, but if you're interesting in being a checkpoint person for next year, we'd love to hear from you," she said.
