Worked decision example

Two different 100-mile decisions

A 100-mile collection is not a set of identical 100-mile courses. These established race identities record about 95 and 105 miles respectively. The figures below come from their selected catalogue editions; the source notes distinguish a next-edition announcement from older detailed rules. More time does not establish an easier race, and average cutoff pace is not a checkpoint plan.

West Highland Way Race

Selected edition: 19 Jun 2027 · 2027
Recorded distance: 152.89 km (95 mi)
Recorded ascent: Approximately 4,499m
Navigation / support: fully marked · semi-supported
Recorded overall cutoff: 35h
Recorded entry fee: £170.00
Recorded entry state: Entries closed · catalogue check 2026-10-18

The next date is announced for 19 June 2027. The FAQ describes about 95 miles and 14,760ft of ascent; the catalogue stores their metric equivalents. The retrieved rules are explicitly for 2026: waymarking, a 35-hour overall limit, checkpoints and crew-supported self-sufficiency are reference information, not a newly verified 2027 guide. Confirm final rules and entry terms; price is unverified.

Montane Lakeland 100

Selected edition: 23 Jul 2027 · 2027
Recorded distance: 168.98 km (105 mi)
Recorded ascent: Approximately 6,300m
Navigation / support: self-navigation · aid stations
Recorded overall cutoff: 40h
Recorded entry fee: Fee needs checking
Recorded entry state: Entries closed · catalogue check 2026-09-04

The organiser’s 2027 overview confirms 23–25 July, about 6,300m climbing, a continuous 40-hour limit and 14 staffed checkpoints. The established 105-mile course identity is recorded as 168.98km, not inferred from “100” in the name. Navigation skills are required. The detailed route page retrieved was still labelled 2026. Ballot or charity-entry announcements do not establish an available place; current price remains unverified.

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 73 current discoverable race records matching the stated geography or distance definition: 73 fixed-distance and 0 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 73 selected fixed-distance race families: 72 with a confirmed start today or later and 1 without a confirmed future start in the selected record. There are also 0 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: 22 of 72
partially marked: 8 of 72
self-navigation: 15 of 72
GPS required: 6 of 72
Navigation not recorded: 21 of 72

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

3 of 72 are recorded as multi-stage; 69 use other fixed-distance formats. Recorded ascent is available for 42, and an overall cutoff or explicit no-fixed-limit statement for 63.

Most frequent recorded terrain labels: trail (70), mixed (55), moorland (29). Labels can overlap on the same course.

The denominator is the same 72 confirmed future starts. Terrain labels do not establish elevation, difficulty or an exact surface percentage.

Build your shortlist

What belongs in the 100-mile collection?

The directory's 100 mile distance band covers 145km up to, but not including, 321.8688km. This is a collection range, not a claim that every race measures exactly 100 mile. Each record retains its own known course distance.

This broad collection brings together courses with different lengths and demands. Compare the recorded distance, navigation, support and night exposure on each race page. A longer overall cutoff does not establish an easier course or tell you whether every checkpoint deadline is achievable.

Use Compare races to look at the same facts side by side. The methodology explains how course assessments and cutoff pressure differ from a personal finish estimate.
