Looks like route planning error. Turned too early, double backed, then missed the turn. Parked up in Burgas now.
GC closes later today right so maybe he feels he hasn't got time, or just hasn't got the energy or inclination to redo it. After 4600km, can't say I blame him.
I think his head was gone. He had bad puncture issues yesterday. I passed him at the side of a main road where he said he'd been stuck for 4 hours.
I saw him roll into the finish. He said he had had more puncture issues through night.
Had been going OK until then.
Oh no.... Oscar you mad lad :-(
