169 entries have been received so far for June's Clerical Medical Parish Walk.
However, last year's winner Robbie Collister and record holder Sean Hands have yet to make their intentions clear.
The latest figure is just a fraction of the numbers expected to take part.
Last year, 1,329 registered to start the event.
