Ranked by the FIETS index of the main climb — the same index each page prints, with its formula.

How this index is calculated

FIETS index: Δaltitude² / (10 × distance) + max(0, summit altitude − 1,000) / 1,000, lengths in metres. How this index works (article in French)

Collect the cols you ride

Sleipnir recognises the cols you cross from the GPS trace of your rides: the col ticks itself off the day you ride over it.
