Bike Drafting – What Happens If I Do It?

In a Nutshell…
-
Drafting during the bike segment can save a significant amount of energy by reducing wind resistance and drag.
-
The World Triathlon rules state that the non-PTO event draft zone is 12 metres behind the lead athlete. If you enter the leading cyclist’s draft zone you must pass them in 25 seconds. If being passed, you have 25 seconds to exit the new lead athlete’s draft zone.
-
If you’re shown a blue card, you are being penalized for drafting on the bike course.
-
You must stop at the next penalty box and serve your required time penalty.
But there is lots more to learn about drafting and the penalties. Want to know more? Then read on through the sections below!
What is Drafting? Drafting in a triathlon is about reducing your drag as an energy conservation advantage. An athlete (or a vehicle) is incurring drag when moving through a medium like water or air (in other words, resistance to their forward progress). However, a trailing athlete following close enough to be in the lead athlete’s wake can avoid some of the full drag effect experienced by that lead athlete. This applies in varying degrees on the swim, bike, and even the run. There are only triathlon drafting rules for the bike segment in a draft illegal event. So, for the purposes of this discussion, we’ll focus on bike drafting.

Do you need a club train/race or social membership for club activities?The CV Tri Club offers the opportunity for individuals to take part in our activities without a membership commitment. Kind of a "try before you buy" concept for the club membership. Tri BC supports our club in this approach as well. But, after a couple of "tries", we’d like you to commit to the "buy". Some activities may have a different fee depending on whether you are a member or not. And there are some social events that only Social or Train/Race club members (and, usually, their guests) are invited to attend.

Can I get a Social membership and still come to club training?This depends on the training, and the answer for an activity may change year-to-year. Refer to the club’s web site Training page for current details. For example, in the Fall/Winter, the Sunday spin sessions have facility insurance and waivers for those activities. So, the Tri BC membership is redundant and a Social membership would be good enough. There are also other activities that are not formal club activities that would be posted on the Facebook page. Examples would be posting awareness of Fall/Winter lane swimming times that some club members often appear at, or impromptu gatherings for a snowshoe or other type of activity. However, there are some club-sanctioned training sessions that need to have Tri BC sanctioning with insurance. In those cases, you will need the "train and race" membership. See FAQ below for more details.
-
Why would I consider getting a club Race and Train membership?Some club activities need to be organized more formally, and therefore need to be sanctioned through Tri BC – which then wraps insurance around the activity for both you and the club. Tri BC is going to want participants in these types of events registered as a Tri BC member (implied in a club train/race membership). But, besides the club activities, the Tri BC and Tri Can memberships offer additional benefits for the added $55 annual fee. For example, an annual Tri BC membership would mean you would not have to pay any event-day Tri BC fees for Tri BC sanctioned races during the race season. To see if their overall membership benefits are of value to you, read more membership information for Tri BC at www.tribc.org/membership and www.tribc.org/membership-registration, and for Tri Canada at www.triathloncanada.com/membership.

Can I get a club Social membership and upgrade to a Train/Race if needed?Yes. You will need to get a Tri BC and Tri Can memberships added to your online registration account. Refer to www.tribc.org/membership-registration and proceed through their registration process. Note that the $5 Tri BC discount for club affiliation is not automatically applied like it is in a normal CV Tri Club train/race registration process. To get this discount, you will need to contact Tri BC (info@tribc.org) to get a discount code to apply at the Order Summary stage of payment.
