Stage 13: Bilbao - Urdax
Stage 13 is for those who dare. It has no fewer than seven categorised climbs (plus another at 30km that must have been forgotten) spread across 213km, the race's longest stage. The break is likely to take the stage but all eyes will be on the GC bunch as the final 30km is ambush territory, with a cat 2 climb and a 5km plummet to the line.
