Triathlon is probably the best known multi-sport event involving the completion of three continuous and sequential endurance events. Whilst there are many variations of the sport, triathlon, in its most popular form, involves swimming, cycling, and running in immediate succession over various distances. Triathletes compete for fastest overall course completion time, including timed transitions between the individual swim, bike, and run components.

Triathlon races vary in distance, the most regular raced distances are:-
Super Sprint, 400m swim, 10k bike, 2.5k run
Sprint, 750m swim, 20k bike, 5 km run
Standard, commonly referred to as “Olympic distance” 1.5k swim, 40k bike, 10k run

There are also longer distances raced, these being
Long Course, better known as Half Ironman, 1.9k swim, 90k bike, and 21.1k run
Ultra 3.8k swim, 180k bike, and a marathon: 42.2k run. Better known as Ironman
Whilst these are the recognised distances there are still many races where one of the components is of longer distance with another component of a shorter distance.

Transition – this is the area positioned both between the swim and bike segments (T1), and between the bike and run segments (T2) and are where the switches from swimming to cycling and cycling to running occur. These areas are used to store bicycles, performance apparel, and any other accessories needed for preparing for the next stage of the race. The time spent in T1 and T2 is included in the overall time of the race. Transitions areas can vary in size depending on the number of participants expected for the race.

Race Licence – if you decide to enter any races you will generally be required to be racing with a BTF license. Whilst Striders of Croydon is affiliated with the BTF it does not cover individual race licences like it does with running races. You can normally purchase a day race licence for approximately £5 when you enter the event or you can purchase a year long licence through the BTF at a club rate here for approximately £40. There are a number of benefits that can be gained by joining so it is worth reading up on the website.


If you don’t fancy swimming then fear not you can always compete in a duathlon which generally comprises of run, bike, run. Again there are two transitions, run to bike and bike back to run.

Again there are multiple distances to choose from:-
Super Sprint, 2.5k run, 12k bike, 2.5k run
Sprint, 5k run, 20k bike, 5k run
Standard 10k run, 40k bike, 5k run,
Ultra, 20k run, 80k bike, 10k run

There are many variations of these distances, including some races having a 100+k bike component, or the longer distance run can be after the bike leg. You can commonly find trail duathlons which would require a mountain bike or cyclocross bike to participate, these will have shorter bike sections as it’s a more difficult terrain to race on.


If you don’t own or can borrow a bike then you can compete in aquathons, this normally being a two component race, swim first then run, although there are some that are run, swim, run.
Super Sprint 200m swim, 2.5k run
Sprint 400m swim, 5k run
Standard 1k swim, 10k run
Aquathons are more commonly held in swimming pools but early in the triathlon season you will find them occurring at open water venues.

If none of that tickles your fancy then there is always the option of taking part in a relay event where you can race in one or two components of the race, you just need to find a willing partner(s). Most of the larger events will give the option of a relay entry, you will race with the individual entries at the same time, the relay part being handing over the timing chip in T1/T2 to your team mate.
