Choose by real demands

Low ascent does not remove distance, weather, navigation or repetitive-course demands. Compare the complete current-edition evidence and format semantics.

Complete directory

All remaining records

The detailed cards above prioritise the next records in this collection. Every other permanent race route remains available here and through the full Explorer.

What is included?

This page includes 29 current discoverable race records matching the stated geography or distance definition: 22 fixed-distance and 7 format-defined. Cross-border families appear only once under their permanent identity.

How are facts checked?

Edition facts retain official-source URLs and a last-checked date. Unknown distance, ascent, cutoff or price is shown as unknown instead of being inferred from another year.

What can you compare here?

As of 7 Nov 2026, this collection has 22 selected fixed-distance race families: 22 with a confirmed start today or later and 0 without a confirmed future start in the selected record. There are also 7 current format-defined families, kept separate from fixed-distance comparisons. These counts describe this directory, not the whole market or places available.

Navigation options

fully marked: 6 of 22
partially marked: 11 of 22
self-navigation: 2 of 22
Navigation not recorded: 3 of 22

One recorded navigation mode per selected fixed-distance edition with a confirmed future start. Use the race record to check the organiser's requirements.

Course and format choices

0 of 22 are recorded as multi-stage; 22 use other fixed-distance formats. Recorded ascent is available for 4, and an overall cutoff or explicit no-fixed-limit statement for 20.

Most frequent recorded terrain labels: trail (20), mixed (11), coastal (7). Labels can overlap on the same course.

The denominator is the same 22 confirmed future starts. Terrain labels do not establish elevation, difficulty or an exact surface percentage.

Two navigation choices in this collection

These are the earliest confirmed future starts with two different recorded navigation modes, ordered by date then permanent identity. They show a choice to investigate, not a recommended order or a first-race suitability verdict.

Compare navigation separately from ascent, surface and the overall time limit. A marked course still has organiser instructions to follow; a longer cutoff does not supply the skills needed for a self-navigated route.
