Points are awarded in reverse order for each event within the omnium. The rider who finishes first in an event receives one point, the second rider will gets two points and so on down the placings. The winner is the rider with the lowest total points. If two riders are tied on points, the combined time of the three time trials will be the tie breaker to determine final placing.

  • Using Field Based Data to Model Sprint Track Cycling Performance Hamish A
    Ferguson et al. Sports Medicine - Open (2021) 7:20 https://doi.org/10.1186/s40798-021-00310-0 REVIEW ARTICLE Open Access Using Field Based Data to Model Sprint Track Cycling Performance Hamish A. Ferguson1* , Chris Harnish2 and J. Geoffrey Chase1 Abstract Cycling performance models are used to study rider and sport characteristics to better understand performance determinants and optimise competition outcomes. Performance requirements cover the demands of competition a cyclist may encounter, whilst rider attributes are physical, technical and psychological characteristics contributing to performance. Several current models of endurance-cycling enhance understanding of performance in road cycling and track endurance, relying on a supply and demand perspective. However, they have yet to be developed for sprint-cycling, with current athlete preparation, instead relying on measures of peak-power, speed and strength to assess performance and guide training. Peak-power models do not adequately explain the demands of actual competition in events over 15-60 s, let alone, in World-Championship sprint cycling events comprising several rounds to medal finals. Whilst there are no descriptive studies of track-sprint cycling events, we present data from physiological interventions using track cycling and repeated sprint exercise research in multiple sports, to elucidate the demands of performance requiring several maximal sprints over a competition. This review will show physiological and power meter data, illustrating the role of all energy pathways in sprint performance. This understanding highlights the need to focus on the capacity required for a given race and over an event, and therefore the recovery needed for each subsequent race, within and between races, and how optimal pacing can be used to enhance performance.

  • Olympic Sprint, Or Team Sprint
    Spectators Summary of Track Cycling Events: (See the USCF rule book or http://www.usacycling.org/ for all the details.) Mass Start or "Scratch" Race: Not surprisingly, all the riders in a Mass Start race start at the same time. The riders all cover the same distance, with the winner being the first rider to cross the finish line at the end of that distance. Although speed is important, tactics and teamwork are equally vital. Groups of riders often take an early lead, and then work together to increase it while their teammates try to block and slow down the "field." On a small track, the leaders may gain an entire lap on the other riders and then join in with the main group again. Points Race: A variation of the Mass Start race, points are awarded to the top placing riders in a series of sprints contested at various intervals during the race. The winner of a Points Race is not necessarily the first to cross the finish line, but rather the rider who has accumulated the most points during the race. Win-And-Out: A variation on the Scratch race where 1st place is decided on the final lap, however, only the winner is finished. In order to secure 2nd place that rider must be first across the line on the next lap. 3rd place is decided on the lap after that. Typically all other places are also decided by this third and final sprint. This makes for interesting tactics. It can be a very hard race if a rider tries gives their all to win only to be forced to continue and try again the next lap.

  • 3/32” Chain Versus 1/8” Chain
    Frequently asked Technical Questions at the track 3/32” chain versus 1/8” chain Q: Is it OK to mix various width cogs and chains? Answer presented by Colby Pearce, former USA Cycling Track Endurance Coach A: NO, it is not recommended in any case. Read on... (Some people mistakenly refer to the width as “pitch”, speaking of “road pitch” or “track pitch”. This is an error. The pitch is the distance between the rollers, and all modern bicycle chain has the same pitch, 1/2”/12.7 mm.) First of all, to use a thicker 1/8th inch (“track width”) chainring or cog with a thinner 3/32nd inch (“road width”) chain is not possible, Women’s Match Sprints World Championship action as the chain is not wide enough and will not engage the teeth on the with Jennie Reed (Kirkland, WA) ahead of Victoria ring or cog. While it is possible to do the reverse and use a 3/32nd Pendleton (GBR) inch cog or chainring with a 1/8th inch chain, it is not recommended because the narrower width of the 3/32” ring or cog will encourage the derailing of the chain from the system during riding. This could cause a crash or at the very least, ruin some equipment, even if you do not go down. In synopsis, there are slight differences to each system, but both are adequate for track use. As a general rule, SPRINTERS should always select 1/8th inch width equipment, but ENDURANCE riders could get away with either. Even riders who “cross over” frequently and are competitive in sprint events are fine to use 3/32nd width chains, as long as they do not train heavily for these disciplines (meaning boatloads of standing starts with weight vests) on the equipment.

  • THE MAJOR Long Before Jackie Robinson, Worcester Cyclist Major Taylor Broke the Color Barrier in Pro Sports
    Bike Culture Magazine www.bikeculture.com Issue 138 (May 2007) THE MAJOR Long Before Jackie Robinson, Worcester Cyclist Major Taylor Broke the Color Barrier in Pro Sports By Lynne Tolman With groundbreaking this spring for a Major Taylor statue in Worcester, Mass., the 1899 world cycling champion’s legacy of trailblazing rolls into a third century. The first African-American athlete to become an international superstar will be the subject of Worcester’s first monument to an African-American, and, it is believed, the first statue of a bicyclist in the United States. Because he was a black man challenging whites in an era of deeply ingrained prejudice, Major Taylor was never guaranteed such honors, despite his extraordinary cycling victories and speed records. In fact, he was largely forgotten for most of the 20th century. How his remarkable story finally came out of the shadows is due in great measure to the efforts of modern-day American cyclists. Marshall Walter Taylor, born in 1878 in Indiana, was nicknamed “Major” as a boy because he wore a military uniform when he performed bicycling stunts outside an Indianapolis bike shop. The shop owner channeled the youth’s talent into racing, and he won his first race in 1892, at age 13. Bicycle manufacturer and racer Louis “Birdie” Munger hired Taylor as a live-in houseboy and factory helper and nurtured his Taylor, back in form again in 1908, the second year of his racing career. Munger became a comeback, at the Buffalo Velodrome in Paris. The father figure to Taylor as well as handlebar extension that he pioneered is clearly visible his employer and racing manager, here.
