Changes 2003: 
Harthill checkpoint (3) has been moved - after 4th stile, turn half right across field to car park by children's playground, instead of half left to follow hedge.  Leaving checkpoint, left on minor road towards main road (take ginnel after pub), cross road, turn left and go right up steps, a signed footpath,  after wide drive.
Approaching the main road before Roche Abbey, there is now a kissing gate on the left.
in Wath-on-Dearne, KwikSave is now Tesco

Changes 2002:
Checkpoint 2 has been moved from Fence to Treeton, 1.7 km earlier, after the footbridge over the railway. 
All supporter's cars to be parked ABOVE the new housing estate, on Washfield Lane, Treeton.

Changes 2001:
At Thorpe Hesley, after going down through a housing estate, work half left past one hedge and up to a gap in a second hedge. Then straight up to the ridge where the path goes left (previously we went half right to the ridgge after the gap in the second hedge).
After Fence, the turn off the main road goes straight onto a cycle path leading to the railway viaduct - yet another annoying 'improved' section! There was a good paddle there!
After Rother Valley Park, the canal towpath from Norwood is open again (last year there was a diversion down the road)
After Swinton, after leaving the side arm of the canal, the new path to Dearne Valley College is now the preferred route (the old route alongside the railway is not viable, especially after dark - it may even be closed off). Up to the road, left, right and pick up the new path (last year under construction) at the first corner.
