Seby locking onto the pink rail at Mammoth Mountain

Mammoth to everywhere after

SEBY SHREDS

Documenting the road to pro.

I'm Seby. I'm 12, I ride at Mammoth Mountain, and on my first day — November 23, 2024 — I couldn't link two turns. Since then: 332 days on snow, all four 540s and my first 720 on snow, Nationals at Copper, and a 900 on the airbag in Japan. My dad films it. This is the whole road, falls included.

332 days on snow / Nationals at Copper / Japan + Austria next / Olympic dream

Start here

The chapter right now.

I'm in Season Two. Mammoth is closed, so the work right now is dryland, trampoline, rail reps, and video review before the Japan airbag block from August to October. After that, Austria closes the season on snow. The goals are all four 720s and at least one 900 on snow — goals, not promises.

Hi

I'm Seby. I'm 12. I ride at Mammoth.

My first day ever on a snowboard was November 23, 2024. I couldn't link two turns without falling. My dad started filming everything anyway — the falls, the run-ins with the snow, all of it. That turned into this site.

I'm not pro. That's kind of the whole point. This is what it actually looks like to start from zero and try to get there, one season at a time.

Season One / 2024–25

157 days at Mammoth. Zero to 540.

Mid-November to mid-May, basically living on the mountain. It started ugly — falling on flat ground ugly. Then turns clicked, and after that everything started stacking.

  1. Linked turns first. Then 180s.
  2. 50-50s on tubes, then real rails and boxes.
  3. First 360 — then I took it to Forest Trail, an actual jump.
  4. First 270 off a rail (the Snowboard Addiction setup at home is why that worked).
  5. Spring: my first 540, at Mammoth.

Season One / The bridge

Hood, then Japan. 720s — and one 900.

After the Mammoth season: six days on snow at Mt Hood plus seven on their airbags. Then Japan — eleven days on airbags. That's where the 720s came, and one 900. On the bag, not snow. I want to be exact about that. But now I know it's in there.

The stuff that doesn't look like snowboarding mattered too: an hour on the trampoline four days a week for months (that's where air awareness comes from), the Snowboard Addiction jib setup in the yard, and 26 days on the jib my dad built. It was pretty homemade. It helped anyway.

Season Two / Right now

The fight to get it back.

Season Two started with no snow. For months the park was rails and jibs and exactly one hip jump. Real jumps didn't show up until January — and by then, after barely touching snow since May, my 540 was just gone. Getting a trick back is its own grind. Nobody films that part.

It came back. And then some — 169 days on snow this season so far:

  1. All four 540s, on snow — regular and switch, both ways.
  2. My first 720 on snow.
  3. Rode Nationals at Copper Mountain — 8th in halfpipe.
  4. Switch rail tricks got strong: 270s on and off, pretzels.
  5. Front boards feel solid. Everything looks way more natural now.
  6. Current favorite: switch back blunt, 270 out.

The scoreboard, so far

The numbers don't lie.

The goals

Consistent 5s, all four 7s, and at least one 9 on snow.

Season Two isn't over

Japan. Austria. Then the two-year mark.

My season ends November 18 — my last day on snow in Austria. Five days after that is my official two years on snowboarding. Between now and then: Japan from August to October, around 64 days on airbags. The goals for the rest of the season: consistent 540s, all four 720s, and at least one 900 on snow. Goals, not promises. That's the sport.
