It looks like his tracker only plots the last 50 points, so his last recorded point now will always be number 50. This means that the first few points from St. Bees have now been erased so the whole route now won't be there for anyone to look at or see when he started.
The points seem to be about every 10 minutes, which really shows the difference between the easy track from Ennerdale Water to Black Sail Hut and then the climb up towards Honister. Will be watching later to see how he gets on in the dark probably after Grasmere.
EDITED to add....only the last 50 points are showing but if you go to the left hand side of the screen you can click between pages so you can see the first points after all.
