All Centurion qualifying races must be sanctioned by the Centurions1911.
The race must be held in Great Britain on a pre certified (measured) course and must satisfy the Centurions1911 regarding health, safety and suitability.
The race must be an "open" race.
The organisers must apply to the Race Walking Association for a race permit (which must be displayed at the race venue)
“B” Rule Racewalking
This is a racewalk.
The Contact Rule: Each walker must have at least one foot in contact with the ground at all times.
In races of 100 miles or 24 hours, the rules differ slightly in that these races are “B” races meaning that no walker will get disqualified for bent knees. However, some judges find that bent knees plus a high turn-over rate makes continuous contact difficult to judge.
The judging criteria is simple: we expect each walker to walk honestly in such a way that he/she is not gaining an unfair advantage over other competitors through his/her mode of walking.
