Sinister 7 Ultra may be the greatest challenge of your life. The 100 mile (161km) course will take you through the most rugged, remote and beautiful terrain in Alberta’s stunning Rocky Mountains. With over 6,300m of elevation gain across the course, this race will punish those who are not prepared. For 2020 we are introducing a 50-mile course option for soloists.

The Sinister 7 is open to solo runners or teams of up to seven and racers have 30 hours to complete the gruelling event. The course is split into seven stages, each featuring a geographic and historic highlight of the area. The race’s name is inspired by the treacherous Seven Sisters Mountain that looms over much of the course.

I just ran this event. This was my first attempt at a 100 miler. What an amazing event. The setting -Canadian Rocky Mountains- was spectacular. The organisation was amazing. The volunteers were absolute gems. What a really cool event. Like somebody else said more single track would improve things but the scenery, the toughness, and cool factor of this event is what makes it, rather than amazing single track. There are not many hotel rooms to be had in the area so book motels and hotels well in advance. I booked a spot at the Lost Lemon campground about 3 months before the event. That campsite was great and really close to the start. There is plenty of camping. I made it to 70.5 miles. Was really happy with that and it was great practice for my next 100 mile attempt! The solo event had a 44% finish rate this year which is the highest yet. I recommend this as a challenging event, one to strive to finish if you are a middle of the pack runner. I'd love to go back and finish it.

I just ran the Sinister 7 last weekend and am so excited to come back next year!! The race was well organized, the course was extremely well marked, and I felt supported and had a great time! The community of racers were welcoming and the volunteers were encouraging. I like the area and the trails, not a huge fan of the gravel road sections.
I will definitely come back next year.

I ran this in 2015 and 2016. I love this race and I love this area. That said, I grew up in S. Alberta so I am biased. I met another runner this past year who wasn't impressed and wanted to DNF so they could go on another hike in nearby Waterton Park.

It is a tough race, deceptively so and I have yet to finish it, though I have finished several 50Ks, a 50 miler, and a 100 miler on other courses.

The volunteers are friendly and helpful, though not always knowledgeable about the cut off times. In 2015 I was told that I missed the cutoff when I hadn't (we figured it out rather quickly), and in 2016 I was told the cutoff was 2 hours earlier than it was. Mentally that is a hard thing to process. The organizers are great and the race is well organized and prepared.

Though not a "perfect race" I would give this a rating of 9/10 so having to choose between 4 and 5 I choose 5.

I've run this race twice as a soloist (2015 and 16) and once on a two person team (2013). The race is impeccably organized, you can camp at the start and finish areas, there is food before and after the race. Aid stations are well stocked. The community feel of the race is unmatched.

I ran the sinister 7 relay as a mixed team of 7. I hadn't ran a race in years and really didn't know what to expect. The organization from registration to the finish line was impressive. Each TA was stocked will all kinds of items that the "sinners" might require after of during their race. The TA common area for legs 2-4 was perfect for my family to hang out for the majority of the day and plenty of space for tents and team gathering. I hope to be back next year!

S7 is one of the premier ultras in Canada. Fantastic mountain setting with killer, relentless climbs, creek crossings, rocky descents and amazing views. The organization is superb and RDs are responsive to feedback as evidenced by little tweaks they have done over the years. Environmentally conscious (bring your own cup/bottle for aid stations) and excellent sponsors.
I have done S7 on a team for 6 years and finally went solo this yr...my first 100miler. Loved it. 7 years and counting...
NOTE: this race is so popular that the team registration sells out in about 2-3 minutes so you better be online when registration goes live. Not a big deal for soloists.
If I could improve 1 thing it would be increased single track....there is a lot of quad trail but it's still amazing
BTW the other race by SinisterSports in just as good if not better (if that is possible)....check out BlackSpurUltra...100km of awesome in Kimberly BC. Did it as solo but like S7 can also be done as a team (6).
Looking forward to next yr at the races 10th anniversary which will be huge!!!

One of the most well supported and challenging races I've done! I'd recommend that you book your stay well in advance (one year) or camp either near the Crowsnest Pass Sport Complex or Blairmore (T2/3/4). Every leg affords a different challenge and it's a great community atmosphere both during the run and as a spectator. Everything from the pre-race meal to the photos at the finish line are handled by the organizing team and the course is very well flagged and laid out.

So this is my first "ultra". I ran leg 6 at night. My team of seven and myself really enjoyed the entire weekend. Everything was super organized from the welcome dinner on Friday to the volunteers throughout the race. As I mentioned, I ran at night and was excited about how well the course was marked. It made for a great night of running and I'm going to do it again. CP stations were excellent, in fact I was surprised how great they were. People running the race were kind and the volunteers were first class - made me feel like the first overall finisher. Tyvm Sin 7. I'll be back next year.

I ran this race as a soloist in 2016. It's among the gems in trail running events, well organized and extremely professionally run race. The course is stunningly beautiful and also challenging - the Canadian Rocky Mountains. Volunteers are exceptional, I run a lot of trail races but have not seen volunteers as much invested in a race success as at Sinister 7. Aid stations supplies and food was great, water and ice also provided. The race is extremely well marked, which is such help at night and in the mountains when you do not know the area. I think that we were lucky this year with the weather, as always in the mountains the weather can be a factor. Communities around Crowsnest Pass are friendly and welcoming. Book your stay early, if you're not camping, there is not that many places to stay in the area. The race organizers made a fantastic move to put the campground next to the T2/T3, if you're camping, it's very close to the start and T2/T3. Logistically for the support crews this race is easy enough to orient yourself, and find your way in a new place. The relays sell quickly, so do not procrastinate. It's worth the travel, plus it's one of the rare races in North America that brings 6 UTMB points if you're looking for that. Agree with the rating of 'Advanced', it's not easy for sure, do your homework running vertical and power hiking, it's not forgiving. Love the medal and colorful bib #. Would love to go back.

This was my first time running this event and I ran it on a relay team. I ran Leg 3, one of the tougher legs. The views are amazing and the people are even better. This had to have been the most well supported event that I have ever been a part of. Our team had a blast and the support on the legs was great. Book your accommodations early and if you can volunteer it not only gets you in early next race but also helps this amazing race go off with out a hitch. Weather was perfect this year I am told. I can't wait until next year.
