BMX bike racers rise through the ranks
BMX racing started life in Los Angeles in the USA as an alternative to motocross racing and quickly became a popular worldwide sport enjoyed by thousands.
Today BMX races are typically held on purpose-built racetracks that have various hills and jumps with banked corners or berms.
While BMX racing is primarily an individual sport, teams are often formed and clubs are usually family friendly with riders aged anywhere from five to 90 years.
There are a number of regional, national and international bodies that provide rules for competition and organised events as well as setting out skill classifications and other regulations.
In the UK, BMX bike racing is overseen by the British Cycling Federation, which provides rules and guidelines for holding events that include a code of conduct, membership and licencing, track competition standards and penalties for infringements. Details of BMX rules and regulations can be found here.
Riders make a point of entering BMX races
Competition riders can notch up points by taking part in organised BMX races and eventually achieve a ranking based on placement at the end of a race event.
Competitors in Olympic and World Championship events can earn the highest ranking points while other events such as international, national and regional races have their own point scales.
Up-to-date ranking for BMX riders are maintained in a database run by British Cycling and points are updated daily.
A BMX bike racer's ranking is calculated from the 12 best results in any one year, where the racing year runs from December 1 to November 30.
Racing points earned in Olympic, World and European championship events are automatically added to a rider's rankings, but British Cycling has to be informed of any points scored at other international events.
Only BMX riders with a full racing licence can be awarded ranking points so anyone planning to take part in competitive BMX bike racing should consider being a fully authorised member of British Cycling.
Membership usually includes a provisional racing licence which will get riders into most BMX races but any race wins will not count towards ranking.
BMX racing is for all ages and abilities
BMX racing is a great cycling sport to both participate in and to watch with categories for all ages and abilities, and there has been a surge in BMX track building around Britain and overseas.
Clark & Kent Contractors has been at the forefront of BMX track design and building in recent years and has even contributed to drawing up the UCI's minimum track standards as well as constructing the track for the 2012 Olympics.
BMX races are held on purpose-built outdoor and indoor tracks across the country. They can be made of compacted dirt, stone, and tarmacadam and are usually up to 400 metres long and feature a starting hill, banked corners and a variety of jumps.
The Olympic standard track at Manchester's National BMX Centre was remodelled by Clark & Kent to bring it up to top international standard in 2012
But BMX racing doesn't have to take place on such high-level tracks as Manchester. Wherever the event the riders and public can be assured of relentless, all-day action, that kicks off with qualifying heats, called 'motos' before entering the knockout stages befoe the final events.
Races generally last well under a minute, and riders take off in quick succession, so it's an exciting day of fast and furious sport for everyone. In Britain, there are regional racing leagues and BMX Series events throughout the year as well as the National BMX Championships.
