The Lone Peak’s Revenge consistently showcases the rugged and challenging character of Big Sky, and this year will be no different. This year’s course features 5 stages over 14.1 miles, with 3,100’ of climbing and 6,500’ of descending. Juniors will do a shorter (7.6 miles) version of the course, skipping stages 1 and 2 (1,100’ climbing, 4,500’ descending).

Transfer 1: Ambush Loop climb. A moderate climb up lower Andesite Mountain to get the blood flowing, mostly on service road. +500ft.

Stage 1: South Fork to Coolridge. The stage starts with a smooth and flowy trail with a couple of sweeping corners near the top. Things quickly get rowdy with a sharp right turn onto a steep abandoned road bed. A short, very steep natural section then leads to an abrupt right hand turn onto the lower Coolridge trail. A combination of tight French-style switchbacks and fast rocky sections leads to the bottom of the stage. Highlights: Pumping the rollers on the buff upper section. Watch out for: Very steep middle natural section that ends in a sharp right turn. -700’. Open 9:15 to 10:15.

Transfer 2: Coolridge to Andesite Summit. A classic character building climb and the hardest climb of the day. The first half is on enjoyable singletrack, but finishes with a burly hike-a-bike. +1500’

Stage 2: Andesite summit to Revenge. Starts with a natural shale section off the actual summit of Andesite Mountain. After a short natural section across a ski run, the course enters the infamous Revenge trail. Sections in the trees are steep with dark soil, and sections in the open are fast and rough. Highlights: The exhilarating “waterfall” section. Watch out for: The initial drop-in when entering the trees is one the more intimidating features of the day. An optional rock drop on the upper section should only be attempted by expert riders (there is a B line). Many steep, tight, and loose sections. The “waterfall” is a super steep section that can be smoothly rolled down (do not air it!) but there is a B line option. -1200’ Open 10:30 to 12:15.

Transfer 3: Swiftcurrent Lift. Enjoy the lift ride and the view!

Stage 3: Yogi’s. The upper half is classic Big Sky. Fast and a bit rocky with alternating open and treed sections. Halfway down the trail crosses the South Road and the real fun begins. After a couple second climb comes a short steep section (one of the steepest of the day) with an abrupt right turn at the bottom. From here is a series of steep plunges through the trees. The final section opens up into a high speed meadow before a memorable finish alongside a cliff. Highlights: This trail is not often ridden, but the lower section in the trees is some of the best DH trail on the mountain. Watch out for: The trail passes the “Swifty drops”, a series of wooden drops that are easily avoided without losing time. A short ladder bridge that can be ridden around. The steep chute after the road crossing. The meadow section is rutted (best to avoid the rut) and has several huge G-outs. The finish traverses above a big rock. Stay left and follow the tape. -1200’ Open 11:30 to 1:15.

Transfer 4: South Road to Jacob’s Ladder entrance. The last long climb of the day will feel easy compared to Andesite. Mostly on moderate service road, but with a short push a bike section in the middle. Watch out for: The route crosses Stage 4. Yield to downhill racers and follow markings. +900’

Stage 4: Jacob’s Ladder, Hollywood, Buffalo Jump, Soulhole. This stage gets faster and easier as it goes, but the start is the real deal. The start is very steep and narrow with a few tight trees to navigate. Keep the speed in check! A right turn onto Hollywood and the steepness continues, but now with more rocks. A short “milkshake” climb that only a few will clean leads to lower Buffalo Jump. From here the angle eases and the flow increases, culminating with the new bottom section of Soulhole which is flow trail all the way to the base. Highlights: Jacob’s Ladder, a forgotten gem. Watch out for: Arm pump. Some rollers near the bottom that might buck a bit. -1500’ Open 12:15 to 2:30.

Transfer 5: Swiftcurrent Lift to “The Bowl”. Take advantage of the lift ride to rest tired legs (and hands). However there is one final hike across alpine terrain to get to the top of stage 5 in the spectacular cirque below Lone Peak. +300’

Stage 5: Black Rock Gully to Nameless to Rabbit Run. The queen stage with three distinct characters. A spectacular and raw alpine start. The rough and challenging Nameless Trail. The fast, fun, and flowy Rabbit Run leading to a finish right in the center of the action at the base area. Highlights: Stage start in the shadow of Lone Peak. Watch out for: A few sections of service road and intersections to navigate. Heads up! -1800’ Open 12:45 to 3:30.
