Equipment Recommendations [top]

A race in late August is nearly guaranteed to be warm and you can expect humidity. Our general guidance, for nearly every race, is to bring everything you think may need, even if you’re pretty sure you may not need it! In short, be prepared for any and all weather conditions. 

The Swim: The lake swim will be wetsuit legal, and we recommend a full wetsuit (it won’t be too hot). It’s a single loop swim, which is longer than most competitors will have done. And the lake is quite long, so if the wind’s right, it could really make for a choppy swim. Tinted goggles please!

The Bike: The course is a mix of climbing and time-trial riding, so you’ll need to be prepared for both. Bonus that the roads in are so smooth, you enjoy the ride no matter what part of the course you are on. 

There are early rollers and one singular hill on 117 that require patience. But the climb out and back (and UP and DOWN to Lac Superior is the real deal. There are plenty of sections with grades north of 10% — even a section with 15%. What takes you 40 minutes to climb only takes 15 minutes to descend, so have fun!

For gearing we nearly always recommend a compact crank (50/34) or “super compact” (52/36) if you’re a bit of a stronger rider on an 11 speed bike. For Tremblant, everyone should have at least a 27- or 28-tooth cog on their cassette (for example, a 27-11 for stronger riders), with less strong riders always benefiting from a 28t or higher (for example, a 28-12 cassette).

In addition to managing the hills, you’ll need to be comfortable descending. Be sure to practice on your local roads and a little bit on race week as well!

The Run:  This course is a great mix of climbing and running on a former rail trail.  Each loop starts and ends with climbing — so be smart — but in between you can stretch you legs on the bike path. There’s a slight descent out / false flat back, so don’t think your mind is deceiving you. 

Your overall experience here will be dictated by both of your bike pacing and the weather. Hot days will make things much harder (but a safer bike) but some clouds certainly wouldn’t hurt your run performance!


Swim Course Breakdown  [top]

The Mont Tremblant swim is a one-loop affair in Lake Tremblant, from a beach start. You’ll swim directly out from shore about 1800m, turn right and swim about 200m, turn right again and swim the remainder back towards the separate swim exit area.

The Temps: The water temperature is pretty consistent in the upper 60s / low 70s. We recommend a full wetsuit. Some athletes opt to wear long john wetsuits, but it’s really your personal preference.

Please Note: By the time you exit transition at the mount line, you will have covered more than a 1/2 a mile!

Bike Course Breakdown [top]

Area 1: Montee Ryan Out to 117 — This is your first chance to blow the entire race. IGNORE the hammerheads and others racing, be safe and just get out to 117. The hills are steeper on the way out, and as a result will take more work than you should be ready to give. Same drill when you come back into town and start lap number two, but you’ll be much more tired.

Area 2: 117 Out/Back + St. Jovite —  If you reference the bike course profile, you’ll see the rolling to flat section that is 117, book-ended by two climbs (same climb just either side). On the way out, you have a 3-mile effort at roughly 3% to 4%. On the return trip, this climb is just 1.5-miles long, but more like 5% to 6%.

In between this climb you have a flat to rolling section for approximately 24 miles. This is a great place to get super aero and fly. The first lap is generally free, but by lap two the wind here can be quick strong significant and can really slow you down you have over-exerted early on. Just sit down, relax, and get into a really nice groove.

In our opinion, this 24-mile section, which you’ll do two times for a total of 48 miles, is essentially free. Just ride steady, ride your race, and ignore the other athletes around you. The town of St. Jovite is just a quick jaunt with nothing to speak off save for some fans (!)…just shoot in, flip it, and shoot out.

Area 3: Montee Ryan In (From 117) — After your “free” early miles you’ll turn right on Montee Ryan when you start to work your way back towards the resort of Mont Tremblant.  You still have to climb, but these hills are steady with fast descents. Manage this section properly and you’ll be able to carry your momentum halfway up the next climb. You’ll hit the rotary just outside the resort with the DJ / party…and then it’s off to do the serious work.

Area 4: Out / Back to Lac Superior — After a short hill — hey, not so bad! — you are slapped with the meat of this climbing section. It’s a two-mile effort with grades between 3% and 8%. After each mini-climb the road will level out but it never really drops off to give you a true chance to recover before the next climb. You’ll enjoy a break of about a mile of climbing with grades up to 4% before you hit the double-whammy steep climb just shy of the turnaround.

Think 6% to 8% into a 10% to 12% section with a kick up to 15%. Easily 95% of the field will have to stand here to not fall over. Once over that hill you have a brief chance to recover before one more small hill and the turn around. Then it’s flip it and bombs away down the entire section.

As slowly as you will have to climb this area, a good descent will help you regain a ton of time. Just be careful as the road is narrow here and can be dangerous. As you head back towards the resort, you’ll pass the Bike Special Needs area and enjoy some really great support from the crowds.

Run Course Breakdown [top]

The run course is very similar to the bike – there are places to go fast and places to suffer. Places to have fans and places to be very…much…alone. It’s a fair course with adequate ups, downs and flats such that most people can still run well if they aren’t nuked.

Area 1: Out to Old Tremblant

  • Several steep uphills in the first 2.5 miles.
  • Lots of spectator mojo in the first two miles and many, many athletes run much too fast here. Don’t be one of them!
  • This section eventually turns downhill into Old Tremblant.

Area 2: Out / Back on Rail Trail Once you jump on to the rail trail, you are running some flavor of flat to slightly down all the way to the turn around. Once you flip it you have, surprise, flavors of flat to slightly up back into Old Tremblant. You’ll run past the converted rail station for a quick one-mile out and back section on packed earth (nice!).

Area 3: Old Tremblant Back to the Resort / Turnaround / FinishArea Once again you have to climb back into the resort, but like the bike these hills are steadier and less steep than when running them outbound. Enjoy the descent sections and watch your heart rate. Just put your head down in the last mile. You have two tough climbs, the first you saw on the way out but the second is a new one that comes at miles 13 and 26 as you navigate into the heart of the downtown section to either start Lap Two or hit The Finish.  Just. Keep. Moving.

You’ll stay right to head to the finish, enter the proper downtown area and fly downhill towards the stands and the finish line. Enjoy and don’t forget to live it up in the chute. The finish line in Mont Tremblant is quite spectacular; do your best to get out here and really soak it up all the way to midnight!
