Another retirement! Former Visma, Jayco AlUla & Uno-X workhorse becomes latest rider to call it quits ahead of 2026

The list of riders stepping away from the peloton ahead of the 2026 season continues to grow, with former Norwegian national road race champion Amund Grondahl Jansen now confirming that his professional career is over.

The Norwegian, who spent the 2025 season with Uno-X Mobility, confirmed his retirement through a post on Instagram, sharing footage of himself skiing in the mountains alongside the caption:

“Things you couldn’t do as a professional cyclist. That’s as good a retirement announcement as any, I guess. Preparing for new goals in 2026, getting stuck in with numbers pinned in 6 weeks from now already! Guess where”

Grondahl Jansen was released by Uno-X Mobility at the end of October, meaning his return to a team from his home nation lasted just a single season. With no new contract announced and his own words now confirming his decision, his time in the professional peloton has come to an end at the age of 31.

Grondahl Jansen turned professional in 2017 with the then LottoNL-Jumbo, later Team Jumbo-Visma, where he became a regular part of their sprint and classics support structure. He rode multiple Tour de France editions with the Dutch squad, forming part of the lead-out train built around Dylan Groenewegen and also working in support of general classification leaders such as Primoz Roglic.

His biggest individual success came in 2019, when he won the Norwegian national road race championships. Just over a week later, he added the other major victory of his career with a stage win at the ZLM Tour in the Netherlands. Beyond those results, much of his professional life was spent in a supporting role, valued for his strength on flat and rolling terrain and his reliability in high-speed teamwork.

After leaving Jumbo-Visma, he joined the Australian structure that became BikeExchange and later Jayco AlUla, where his career was repeatedly disrupted by serious health problems, including issues with his femoral artery that required multiple operations. Those setbacks limited his racing and placed him among a growing list of riders affected by that condition.

His final season came in 2025 with Uno-X Mobility, marking a return to a Scandinavian project at WorldTour level. That spell, however, proved brief, and with no continuation into 2026, his Instagram post has now confirmed what had already seemed likely.

For a rider whose career was defined more by service than spotlight, Grondahl Jansen leaves the sport as a former national champion, a Tour de France rider on multiple occasions, and a domestique trusted by some of the biggest teams and leaders of his generation.
