Triathon / Duathlon Rules & Regulations


The inherent honesty and integrity of each participant is respected at Somersault events. The primary responsibility for the fair and safe conduct of a race lies with the participants in the event, not with the race organizers or officials.

All participant personal equipment, apparel, and supplies, are the sole responsibility of the participant; the organizer is not responsible in any manner for this personal equipment, apparel, or supplies.

Somersault events are organized for the participants, and ultimately it is the participants who decide how they will conduct themselves during the competition. It is each participant's responsibility to know and to adhere to Somersault event rules, respect other participants, and to compete fairly and safely. Please take the time to become familiar with these event rules and protocal.

Somersault event rules exist for two reasons. The first is to ensure the safety of the participant. The second is to ensure that the competition is a fair one for all participants.

The rules represent the set of race conditions that have been decided on by our insurers, the sport, common sense, and by past participants. To participate in a Somersault event, each participant must agree to follow the rules set out here, or as are explained in our event orientations and on the event web sites.

Anyone failing to follow the rules of the event is either putting someone at risk, or is gaining an unfair advantage - neither of which is acceptable. Where the rules are infringed, penalties will be applied by the organizer. The primary responsibility for rule adherence lies with the participant.

When witnessing a rule violation by another participant, you should request that it stop. If that fails, you should report it to a race official.

It is important to understand that Somersault Event Series (2251389 Ontario Limited), and any of the organizations, businesses, or individuals participating in the organization and presentation of this event are not liable for lost, stolen, or damaged apparel, or equipment. The participant is solely responsible.

By registering for an event and agreeing to the participant waiver, the individual(s) understand that the event does not carry/cover personal accident insurance for participants.

Ipods, MP3s, Walkmans and Headphones
We do not allow the use or wearing of Ipods, MP3s, Walkmans, or head phones during the cycling portion of Somersault Series Triathlons or Duathlons. Wearing one during the cycle portion of the race will result in disqualification.

We also discourage the wearing of Ipods, MP3s, Walkmans or Headphones, etc, during the run portion of Somersault events. These devices may prevent you from hearing instructions from marshals, from hearing other participants, or vehicles, and may put you at risk.

We do know however, that many of you wish to wear these devices during running events, so we do allow you to wear them during the run, but advise you that you do so at your own risk. If you use a head phone or an ear phone device, you should only have the hearing device in one ear. This is to ensure you can hear the directions of marshals, officials, and vehicles.

a) Bicycle helmets are compulsory for all cyclists. The helmet must be CSA, or equivalent to CSA, approved,

b) Helmets must be worn and chin straps must be fastened before a competitor mounts the bike. They must remain on and fastened until you dismount from the bike.

a) Competitors should only receive assistance in the transition zone when it is administered by medical staff, or race officials. On the race courses, assistance may be administered by spectators or friends when it is obviously required by the participant. This assistance must not involve carrying, transporting, or pacing the individual, or allowing them to "draft".

a) Competitors must cycle alone and unaided by other cyclists or motor vehicles. Rules defining drafting and the accepted procedures for avoiding drafting can be found in "Drafting Rules and Procedures " section below.

Wetsuits are allowed at all Somersault Triathlon Series events, regardless of water temperature.

Water Temperature
If water temperature on the morning of any of our Triathlon events is at 67 degrees or below, participants will have a "no questions asked" opportunity to move their race entry to one of the Duathlon events we offer. Should the water temperature drop below 65 degrees, all Triathlon events will automatically be turned into/rolled into one of the Duathlon events we offer. For awards and champions challenge ranking points, there will be two separate sets of results for each duathlon distance - one for those originally registered in the actual duathlon and one for those originally registered in the triathlon.

a) Competitors must have their torsos covered during the bike and the run portions of the event.

b) Competitors must place their bib numbers on the back of their jersey during the cycle and on the front during the run. Bib numbers must be visible at all times. Email us for ideas on how to do this.

c) Competitors must wear a swim cap during the swim. It will be provided by Somersault - or you may use your own. The swim cap must be marked with the competitor's bib number (at the body marking tent in the Transition Zone).

d) Competitors must ensure that their swim cap and their bodies are marked with their bib number. A body marking model and markers are provided by Somersault in the Transition Zone to allow competitors to mark themselves properly.

e) Competitors may not be publicly nude at any time during the competition.

Other Rules:
There are many other rules that govern the competition. These are covered under the rules of the sport as defined by TRICAN. We generally adhere to these rules except where they may differ from our own. A copy of these rules can be viewed by going to

Consequences of Breaking the Rules:
The consequence of breaking the above and other rules of competition will depend on the severity of the infraction, and will be entirely at the discretion of Somersault race officials.

Jury of Appeal:
Competitors who feel they have not been treated fairly according to the rules of the competition, or who may wish to lodge a protest against another competitor, must submit a written appeal, to the Race Director before the awards presentations, or within a reasonable period after the event or occurrence. A Jury of  Appeal will be appointed by Somersault to hear the protest /appeal. The Jury will be comprised of a Somersault representative, race director, and participant. The Jury of Appeal's majority decision will be final.

Drafting rules and procedures
Bicycle drafting is against the rules in all Somersault Series events. Refer to Section E.2 in the TRICAN rule book for a detailed description of the drafting rules and procedures.

Many participants do not understand what bicycle drafting is. This rule section has been added to provide everyone with the general information they require in order to identify drafting and to avoid doing it. Cycle course officials will be on motorcycles on the bicycle course at Somersault events.

In many Somersault races, there are too many cycling participants to allow everyone to avoid drafting situations. We recognize this fact, and officials will not unnecessarily disqualify participants in such situations.

The rules below are guidelines. Somersault event officials are experienced in determining whether an advantage is being gained or not, or whether the drafting is purposeful or not. They will make decisions on that basis and their instructions must be obeyed, or disqualification will result.

Drafting Definition:

    • Riding within 5 metres of someone's back wheel is drafting
    • Riding beside someone within 2 metres is drafting
    • Riding next to someone and not overtaking them or dropping back from them constitutes blocking

How to Avoid Drafting:

    • You are allowed 15 seconds in someone's draft zone while passing
    • If passed you must drop out of the passing cyclists draft zone before re-passing them
    • You are considered "passed" when a competitor's front wheel is ahead of yours.
