Thymen Arensman, the climbing-and-time-trial all-rounder for INEOS Grenadiers, geared his 2026 toward a fourth Giro d'Italia start, building through the spring stage races before peaking in Italy. The Giro became the centrepiece of his season: his standout day was the Stage 10 Viareggio–Massa time trial, where he finished second behind teammate Filippo Ganna, a result that vaulted him into the podium fight. He carried third overall deep into the race before the Dolomite queen stage cost him a place to a resurgent Jai Hindley, and he finished fourth overall at +7:02 — a career-best Grand Tour and a breakthrough as a protected GC leader, aided by former champion Egan Bernal's pacing in the final mountains. The platform is set for a tilt at the Tour later in the year.
Arensman survived a late scare. When Gee-West and Hindley attacked on the final climb and briefly threatened his fourth place, it was teammate Egan Bernal who paced him back into contact. He finished 5th on the stage and held fourth overall at +7:02 — a fine first Grand Tour as a protected GC leader.
A costly day for the INEOS man. Unable to follow when Gall and Vingegaard lifted the pace on the final climb, Arensman conceded more than a minute (12th at +1:45) and slipped from third to fourth overall, leapfrogged by Jai Hindley. He now sits 4th at +5:33 with only Piancavallo left to try to win the place back.
Arensman was present in the elite group when Vingegaard went clear and launched his own attack from the chasers inside the final 2 km. Only Gall and Hindley could follow, and Gee-West rejoined before the flamme rouge. He took fourth on the stage and, crucially, climbed to third overall at +4:27, putting himself squarely in the fight for the final podium.
Arensman limited his losses to 1:23 on the stage, sixth across the line, but it was enough to cost him a place on GC. He dropped from third to fourth overall as Gall leapfrogged him, now sitting at +3:03 behind the new leader Vingegaard.
The day's biggest GC mover. Arensman set the early benchmark among the overall contenders and never relinquished 2nd on the stage, completing an INEOS 1-2 at +1:54. Crucially he gained more than a minute on Vingegaard, climbing from outside the podium into 3rd overall, now exactly 1:30 behind the Dane and ahead of Felix Gall. A statement TT that reframed his Giro as a genuine GC campaign.
Arensman limited his losses well on the summit finish, coming in fourth on the stage at +0:34, same time as Piganzoli. He moved up to sixth overall at +5:00, consolidating his place among the GC contenders behind the leading trio.
Second overall starting the day, Arensman couldn't follow when Pellizzari attacked and Storer lifted the pace on Montoppio. He lost ground at the critical moment and slipped from second to third overall at +50, ceding the runner-up spot to teammate Bernal — a frustrating end to an otherwise consistent week.
Arensman finished safely in the GC group at +20, sitting second overall just four seconds off Pellizzari with one stage to go. INEOS held two cards in the top three (Arensman and Bernal level on time), but Arensman would be the one to crack on the final climb the next day, dropping to third overall.
INEOS's GC leader for the race, Arensman was the only rider able to follow Pellizzari to the line at Val Martello, taking second on the stage and sitting within a handful of seconds of the lead. He would hold a podium position all week before cracking on the final climb to slip to third overall.
INEOS's nominal leader rode a consistent week — second behind Pellizzari at Val Martello, in the GC group throughout, and runner-up overall into the final day. But he couldn't respond on Montoppio when Pellizzari attacked and Storer lifted the pace, dropping to third overall behind teammate Bernal. A solid Giro tune-up undercut by the final-climb crack.
Arensman was fifth in the Vilamoura ITT, the best of the climbing-GC types behind Ayuso and Seixas, moving up the overall. He finished ninth on GC as part of a strong INEOS collective showing.
Arensman was ninth overall and INEOS's third rider in the GC top ten, fifth in the Vilamoura ITT. Part of the team's collective strength that delivered the team classification.
