Mario Grob

Oslo Vinterpark With A Youth Olympic Bib

The Oslo Vinterpark pipe was cold, blue-edged, and loud under the February light. Mario Grob dropped into the wall for Switzerland, carrying speed through the transition and trying to keep the next hit alive before the flat bottom stole momentum.

His 2016 Youth Olympic halfpipe result remains the clearest marker in his public record. Grob finished sixth in boys’ halfpipe at Oslo, then also started boys’ slopestyle at Hafjell, where he placed 17th. That combination put him inside Switzerland’s park-and-pipe pipeline during a period when freeski judging was becoming sharper, more technical, and more specialized.

Ennetbuehl In The FIS Record

FIS lists Grob as a Swiss freestyle skier from Ennetbuehl, born in 1999, with athlete code 2532431. His recorded disciplines cover halfpipe, slopestyle, and big air, although his strongest finishes cluster clearly around halfpipe.

The first FIS result in the available record is a European Cup slopestyle start at Stubai in November 2014. By spring 2015, he was already appearing in Swiss national championship events at Corvatsch, placing ninth in halfpipe and 16th in slopestyle. Those early starts show a skier testing both wall-based and course-based formats before halfpipe became the center of his best results.

Copper Mountain Before Lillehammer

Before the Youth Olympic Games, Grob’s record includes two FIS halfpipe starts at Copper Mountain, Colorado, in December 2015. Copper is a serious early-season pipe venue, with hard winter snow, a large pipe, and international fields using the same site for pre-season progression.

Both Copper starts ended in 20th place, but the location matters. A Swiss junior traveling to Colorado for halfpipe contests gets a different rhythm from home events: faster walls, larger amplitude demands, and judging panels used to seeing North American pipe depth. Those starts came two months before his Youth Olympic appearance in Norway.

Sixth In Oslo, Seventeenth In Hafjell

At the 2016 Winter Youth Olympic Games, Grob placed sixth in boys’ halfpipe with a best score of 64.00. The event was won by Birk Irving of the United States, with Finn Bilous of New Zealand and Trym Sunde Andreassen of Norway completing the podium.

Five days later, Grob also appeared in boys’ slopestyle at Hafjell, finishing 17th. The slopestyle field had a different competitive profile, with Birk Ruud, Alex Hall, and Finn Bilous on the podium. For Grob, the week showed both range and direction: he could start across park formats, but the halfpipe result carried more weight.

Crans-Montana Became The Halfpipe Checkpoint

After Norway, Grob returned to Swiss events and added a fourth place in FIS halfpipe at Crans-Montana in March 2016. One year later, the same resort became a bigger checkpoint when he finished 10th in halfpipe at the 2017 FIS Junior World Ski Championships.

Crans-Montana is useful context because it places his development inside Swiss competition terrain rather than only one Youth Olympic week. Junior Worlds are a deeper test than a local FIS event. A 10th-place halfpipe finish there confirmed that Grob’s Youth Olympic result was not an isolated entry on the record.

Laax, Davos, And The Swiss Pipe Circuit

Grob’s record repeatedly returns to Swiss venues: Laax, Crans-Montana, Davos, Grindelwald, Corvatsch, and Silvaplana. Laax appears through national championship and European Cup halfpipe starts, including ninth in the 2017 Swiss national championship and 13th in the 2018 European Cup halfpipe.

That venue pattern matters for his profile. Swiss halfpipe development depends on access to a few specialized parks and pipes, where riders learn wall timing, takeoff pressure, left-and-right hit rhythm, and clean landings through repeated laps. Grob’s result list shows that circuit clearly.

Two FIS Wins In 2018

The strongest cluster of Grob’s competitive record came in early 2018. On January 28, he won a FIS halfpipe event at Crans-Montana. On February 25, he won another FIS halfpipe contest at Davos.

Those wins did not place him among global freeski headliners, but they show the discipline where he had the most traction. Halfpipe rewards rhythm more than isolated tricks. A skier has to keep speed through both walls, hold grabs without breaking axis, and land high enough on the transition to make the next hit possible. Grob’s best documented results sit inside that exact skill set.

Grindelwald With Pipe And Big Air On The Same Day

On February 2, 2019, Grob produced one of the most complete days in his FIS record at Grindelwald. He placed third in halfpipe and fourth in big air on the same date.

That pairing gives a useful technical snapshot. Halfpipe demands repeated amplitude, wall rhythm, alley-oop awareness, and stable landings. Big air compresses the task into a single jump, where pop, axis control, grab security, and ride-away quality decide the score. Grob’s same-day results show comfort with airtime in two different judging formats.

Warmtobel And Davos Beyond The Score Sheet

Grob’s public trail is not only FIS tables. Downdays documented him at Warmtobel Jam in 2016, describing a hand-built Swiss park session and captioning him on a 540 over the hip. That kind of event sits closer to local freeski culture than formal competition.

Skipowd later lists him in Davos Raw, a 2026 park video with Nalu Nussbaum filmed at Jatz Park in Davos. The page describes a full day lapping the park with Andrea Pedrazzetti behind the camera and Grob appearing as a special guest. It is a small marker, but it keeps him visible in Swiss park footage after his active FIS period.

The Record As It Stands

FIS currently lists Grob as not active. His verified competitive arc runs from Stubai in 2014 through Davos in 2019, with the Youth Olympic Games, Junior Worlds, Swiss national championships, European Cup starts, and FIS events forming the core of the résumé.

The cleanest reading is a Swiss halfpipe-first freeskier with enough slopestyle and big air starts to show range. His strongest public markers remain Oslo 2016, Crans-Montana 2017, the two 2018 FIS halfpipe wins, Grindelwald 2019, and later Davos park footage beside Nalu Nussbaum.
