For those who manage to finish the run, the bikes reassemble in the paddock, and the riders sign-off and receive their cup (and by 'cup' I mean a crockery thing ya drink ya tea from!)

Sunrising Hill by todays standards is just a bit of a hill, but way back, this was a serious challenge to motorised vehicles.

Many of the entrants have side-valve low-compression (lousy fuel back then) engines, possibly with only one gear, but more likely to be three, so the Hill for many is tackled in low/bottom gear (if you're lucky enough to have a 3 speed, it has 'low', 'middle' and 'top'). Due to early lubrication systems being somehat limited, many of the bike have to have rider-operated additional oil for inclines where the engine has to labour - this is usually done by the rider operating a plunger pump by hand.

Those riding the really early machines, especially with a sideacar, are often seen tackling the Hill with the help of various folk pushing the machine!!

The more powerful entrants (Overhead valves, a bit more oomph and a selection of gearing etc) can tackle the hill quite easily, but riders are acutely aware of the work the engine has to do.

Every year you post the details of this event & I  think I'd like to go to that.
Then every year it clashes with something else so I don't go.
Every year I look at your photos & wish I had.
