This year's race will see a special start time of 8.45am for those teams who have dressed up, so he advised people to come along then to marvel at people's costumes as they crossed the start line.
Likewise, if people were around the course, Mr Docherty urged them to pop out and cheer on the walkers and runners.
"It's going to be a lot of fun, people get really creative with their costumes, which is always a treat to see," he said.
Fantastic prizes will be up for grabs for those who dress the best, he said.
Walkers start at 8am, those in costume at 8.45am and runners at 9am.
The race will be followed by a prizegiving at the Village Green, expected to be finished about 3.30pm.
