Five weeks at altitude. Every session. Then the two weeks that determine whether the block actually works. Jimmy opens his complete training diary from Park City: acclimatization, heart-rate changes, weekly volume, intensity, the biggest training week, sessions with Mika and Alvar—and the exact plan for the first two weeks after returning to sea level. This isn’t a simplified altitude-training guide. It’s the complete block, the decisions behind it and Jimmy’s honest uncertainty about whether it will pay off.

Part 1 gave us an unfinished Airbnb, a broken car and COVID. In Part 2, Park City finally starts behaving like a training camp. Mika is back in his first proper week of training, Olympic champion Billy Demong gives us a completely reasonable plan for a future SKIRIOUS house, and the crew starts pitching “Project 2034.” Then it is back to work: roller-ski speed, double-pole intervals, Utah heat, Coxa confusion and Alvar getting slightly too close to Mika in a sprint. We finish the week with pickleball, hurt feelings and one final minor injury at the gate. Standard SKIRIOUS operations.

Alvar Alev is back with Mika and Jimmy for a Park City catch-up that moves from serious skiing to completely unnecessary personal conflict. They talk about Alvar changing his training after six years, why Park City keeps bringing him back, what European skiing can learn from the American system, university teams, Soldier Hollow and Utah 2034, Will Koch’s move to biathlon, and the economics behind athlete pathways. Then Mika reveals he is still angry about pickleball. Jimmy explains why Mika is the worst person in the world to argue with. A debate about double poling becomes personal, Alvar gets a front-row seat, and nobody learns anything. This is not a polished interview. It is three elite skiers in Park City with too many opinions and enough history to say exactly what they think.

We came to Park City, Utah, to host the first SKIRIOUS camp and begin a serious altitude-training block. Instead, we couldn’t get into our accommodation, discovered an Airbnb that looked like a construction site, broke the car on the way to our own camp—and then Mika got COVID on day two. Somewhere between the chaos, we still found the best of Utah: incredible trails, roller-ski sessions, proper Western-movie views, steaks, questionable American sweets and the usual SKIRIOUS crew decisions. This is part one of our USA trip. Subscribe and check back next week to see whether Mika can return to proper training—and what goes wrong next.

Mika got sick on the final day of the SKIRIOUS Park City camp, so Jimmy handed the second microphone to Norwegian coach Vetle and opened the floor to the athletes. What began as a quick camp recap became a live coaching clinic: what Norway can learn from American ski culture, why underdogs can build stronger teams, how to plan a sprint heat, when training should feel hard, whether young skiers need to peak, and how to balance skiing with other sports and school. Recorded at Soldier Hollow in Utah, future home territory of the 2034 Olympic and Paralympic Winter Games.

Recorded in the middle of Blink Festival in Sandnes - with four people, three microphone cables and very tired legs - Mika and Jimmy sit down with Blink founder and sports director Arne Idland and IDT Sports' Morten Iversbakken. Morten explains why IDT brings 1,300 pairs of brand-new roller skis to Blink, whether Lysebotn Opp times can really be compared across different years, and why equal equipment, logistics and athlete safety matter. Arne tells the story of how Blink grew from an idea shared with legendary NRK commentator Kjell Kristian Rike into a free city-centre festival owned by the people of Sandnes. The conversation then gets bigger: what can World Cups learn from Blink, why does biathlon appear more willing to change than cross-country skiing, should roller skiing become part of the main World Cup, do we need more race formats - and do we even need classic technique? This one contains skiing, business, city-building, FIS versus the IBU, a proposed Norwegian Olympics and the usual amount of Skirious chaos.
