You don’t go to Death Valley for a vacation. You go to prove that you’re worthy of going head to head with the world’s toughest footrace.

Each July, the Badwater® 135 creates heroes of the men and women who assemble in Death Valley to run 135 miles across the desert and this year, we have created a special-edition R1 tailored to that unique challenge.

Ultralight, Ultra-Focused

For the R135 we switched out the upper of the R1 for an ultralight, breathable, and fast-drying woven mesh fabric engineered for the hot conditions of the Badwater® 135. The result is a shoe that weighs just 7.9 oz / 225 g (US M9), 6% lighter than the original design.

Seen Through the Night

The Badwater® 135 involves running through the night on desert roads. Safety is paramount, so the R135 incorporates a reflective coating on the midsole to enhance visibility for safer racing from dusk till dawn.

Proven to Perform

Underfoot the R135 maintains the tried and true record-breaking formula of the R1: TUNEDFIT Dual Lacing System for on-the-fly fit customization, with dual-zone ZeroSag and LightCELL midsole to boost comfort for the duration of the longest runs.

For 2025, Mount to Coast has been named as the presenting sponsor of the 38th annual Badwater® 135 Ultramarathon. The race is widely considered the world's toughest foot race.

It covers 135 miles from Death Valley to Mt. Whitney, CA, starting at the lowest elevation in North America and ending at the trailhead to the highest point in the contiguous United States.

It covers 135 miles from Death Valley to Mt. Whitney, CA, starting at the lowest elevation in North America and ending at the trailhead to the highest point in the contiguous United States.

In addition to the distance, athletes must deal with huge swings in temperature – Death Valley earned its name by being the hottest place on earth – to massive changes in elevation, from being below sea level at the start to finishing at 8,360 ft (over 2,500 m).

It's a race that requires perfect planning, years of consistent training, and a whole lot of luck just to complete. But those who do reach the finish will have enough stories to last a lifetime.
