The rock is about the size of a house brick, weighs about 3.5kg and is a piece of basalt worn smooth by tidal erosion. When He Yun Chang first picked it up it had some barnacle encrustation which has been worn away by his handling of it.
On Day 017 of the walk (Tuesday 10.10.06) the rock broke in two along an existing transversal fault when he dropped it into the grass on the verge of the A96 at Netherton Farm, near Keith, Moray, Scotland. It was repaired that night using B&Q two part epoxy resin.
Subsequently, it has suffered further wear and tear in the form of flaking along one of its ridges.
He Yun Chang walks for about ten hours each day with rest breaks of about five minutes every one or two hours and a 30-45 minute lunch break. The point at which the walk stops each night is carefully noted and he restarts his walking the following day from this point.
The walk is accompanied by a support vehicle which is a 5 berth Daytona Viking motorhome conversion on a Ford Transit 160 base, powered by a 2499cc diesel engine. Most nights this is also used as self catering sleeping accommodation for the five person tour team, including He Yun Chang, with occasional nights in a hotel or guest house to avoid motorhome cabin fever. So far, nights in the motorhome have been spent at nearby caravan parks for convenience but the van is equipped to be fully self sufficient if the need arises.
