The way points of this bicycle route:
Steep but short start, crack that and it's gentle slope for the rest of the climb.
Downhill now for the next 3km or so. You won't even have to pedal.
1 in 4 down slope here, so take it easy.
And now a 1 in 5 up, to compensate.
Gentler climbing now, the difficult bit is over.
Steep down again, then a lovely easy section along the valley floor.
Another sharp climb, the final one, up to the junction. Just keep turning the low gears.
Gentle climb back up to top.
And it's downhill all the way from here.
