What Part 4 governs

The Union Cycliste Internationale (UCI) Regulations are divided into seventeen numbered parts, which sit alongside the Constitution and the Code of Ethics. Each article carries its own three-part number — such as 4.11.010 — the first figure of which is the number of the part itself. This document is Part 4 of that set.

Mountain bike in all its disciplines: cross-country (XCO), downhill (DHI), enduro (EDR) and marathon (XCM) — covering the calendar, age categories, the World Cup, rankings and teams.

Key changes in this editionChanges from the edition of 10 June 2021

  1. Lifetime personal numberNew article 4.1.049: a rider who wins an elite World Cup race (XCO, DHI or EDR) is required to select a personal number between 2 and 999 for the Mountain Bike World Cup.
  2. Recognition of pregnancyNew articles 4.10.012 and 4.11.022: if a rider takes part in fewer than three rounds of the World Cup in a season by reason of pregnancy, the national federation and the team may ask the UCI to recognise the pregnancy — a mechanism parallel to the one that exists for injury (article 4.11.021).
  3. Complete rewriting of downhill competitionArticles 4.11.010 to 4.11.020 redefine the structure of downhill: at least one qualifying round and one final; qualification of the top 20 junior men and the top 10 junior women from the qualifying round; start intervals of at least 30 seconds in the qualifying round and one minute in the final, rising to two minutes for the last 10 riders; and a final start order based on the reverse of the qualifying-round results.
  4. Compulsory attendance at ceremoniesThe official ceremony is held immediately after each race, and a rider who arrives more than 5 minutes after the end of their own race is fined.
  5. Marathon World CupArticles 4.12.006 to 4.12.010 govern the Marathon World Cup: the top 20 riders in each round and the top 80 riders in the individual XCM ranking obtain places for the Marathon World Championships.
  6. Volume of change91 new articles and 61 deleted articles — the most extensive rewriting among the discipline parts.

Who this document matters to

The mechanism for recognising pregnancy is a new and significant point from the perspective of female athletes' rights: previously only injury held such a status. For teams and federations, the deadline for submitting the request to the UCI is a condition of using this mechanism.
