This depends on the water temperature. As from 2025, British Triathlon rules state that wetsuits are mandatory if the water temperature is 15.9C or below. If the water temperature goes over 22C, which is highly unlikely to happen for open water swims in the South West, then you’re not allowed to wear a wetsuit for Sprint or Standard distance races. For 70.3 or Iron distance events, the water temperature would have to reach 24.5 before you were not allowed to wear a wetsuit.
Sleeveless or shorty wetsuits are permitted but competitors should be aware that they offer less protection against the cold.
Yes they are. However you should be aware that they offer less protection from the cold.
At most triathlons, and all open road triathlons, ‘drafting’ is not allowed. All competitors are meant to stay 12 metres behind the next competitor on the road. But at the Olympics and at Age Group sprint championships and qualifiers, triathlons are run with drafting. People come out of the swim in groups. They are then permitted to work together on the bike leg, taking turns on the front in a peloton, to keep speeds high. On a bike the advantage of drafting can be 30 percent or more.
For safety reasons triathlon or TT bikes are not permitted in a drafting race. You must ride a standard road bike. You also need to ride well to the left if you are on your own to allow faster groups to pass you safely.
We organise two types.
Mixed Relay Triathlon, as seen at the Olympics, where mixed teams of four (two female and two open participants) all take it in turns to complete a super sprint triathlon before tagging their teammate. We organise these twice a year at Torbay Velopark
Standard Relay Triathlon
In this format, offered at most of our triathlons, a team of two or three people each take on one or two of the triathlon disciplines.
See the British Triathlon website for more about relays
As part of the British Triathlon Competition Rules, when taking part in a British Triathlon permitted event, individuals are required to become a member of the sport, hold a race licence and third-party Public Liability insurance. A Race Pass is for individuals who are not annual members of British Triathlon who live within the UK.
Swim Bike Run programme participants do not need to purchase a Race Pass. A Race Pass is included within the entry price of a Swim Bike Run Programme event and is not required to be purchased additionally.

Absolutely not. For many people a sprint distance or supersprint distance is the first triathlon people do as the distances are relatively short and manageable. At the Sprint Triathlons we organise there’s a fairly small number of people going flat out & a lot more who are just aiming to finish. Actually we think the term ‘Sprint Triathlon’ is not helpful & maybe it’s worth considering a new name for them.
Yes, we are keen to get more clubs, companies & charities taking part in our events. If you buy five or more places in any of our events a 10 percent discount will automatically be applied to all the places. We’re also happy to invoice your organisation instead of people entering individually. In that instance we will also waive our booking fees. If you’d like to be invoiced please email enquiries@sportivaevents.co.uk
Yes all our events & road sportives are fully marked with arrows & spray chalk. The only exception is our gravel sportives, the Haldon Heroic and Devon Grit. On the gravel sportives only the short routes are fully marked.
During 2026 we are transitioning to fully cupless events. We now have collapsible TPU cups on sale if you don’t have one of your own or we will of course refill bottles or soft flasks on request. We also strongly encourage people to bring hot drink cups with them for any drinks they plan to get from our event caterers. During the transition period we will have a limited supply of uncoated paper cups available.
No, normally race belts and other merchandise are ready for you to collect at registration.
Overseas residents can not purchase a Race Pass.
Overseas residents are exempt from becoming a member of the sport and holding a race licence when taking part in a British Triathlon permitted event. However, to take part in a British Triathlon permitted event, overseas residents must have their own Public Liability insurance (sometimes referred to as personal liability insurance) in place for the duration of the race the individual is taking part in. The recommended minimum level of cover is £5 million.
By entering a British Triathlon permitted event, overseas residents do so confirming that they will have Public Liability insurance in place for the duration of the race they are taking part in. Proof of valid Public Liability insurance may be requested at the event and in the case of any subsequent third-party claims.
Unfortunately, British Triathlon are only able to provide Public Liability insurance to UK residents. If an individual lives abroad permanently (out of the UK for more than 6 consecutive months in a year) Public Liability insurance cannot be provided by British Triathlon through either annual membership or through a Race Pass. Overseas residents are encouraged to contact their national federation for guidance.
See the British Triathlon website for more information
Unfortunately not. However we have teamed up with Zone3.com who offer wetsuits for hire and for sale.
You can use the code SPORTIVA & get 15 percent off all their wetsuits, goggles & other accessories
They also do a great season hire deal for wetsuits with an option to buy at the end of the season for a discounted price. The SPORTIVA code does not apply to hire suits.
On events where we do a tshirt there is a three week lead time to print the tees. So if you enter less than three weeks before an event t-shirts will not be available.
New for 2026, you are now allowed to lay out towels in transition. Here’s the relevant paragraph
‘Towels may not be used to mark space. but a A single small flannel-sized towel no larger than 12” x 12” (30cm x 30cm), which may be used in Age-Group at any non-elite (Senior, U23, Junior and Youth) events only, that include a swim element. The flannel must be placed either in the competitors shoes at all times, or if they are using the same shoes for all elements, must be rolled up and then placed directly under the horizontal bar of the transition racking, or box if supplied. Larger towels are permitted but must be kept in the competitors bag and placed back inside the bag after use, otherwise a time penalty will be applied.’
If you’re new to triathlon it’s worth scanning through the British Triathlon Competition rules in full, particularly section 7 on transition
Join swimmers from across the South West and beyond for an unforgettable open-water lake swim experience at Wimbleball.
