Ask which NN season was the strongest top to bottom and 2022 wins the argument: a world record, a Tokyo Marathon course record, a Dutch record at the home marathon, a London title and an Amsterdam course record — in the first year the kit carried the INEOS mark full-time.
The season opened with the January INEOS partnership and Kipchoge's Tokyo Marathon win, and closed with his second Berlin world record: 2:01:09 on 25 September. In between, the championships of July were raced in federation kit — Cheptegei in Uganda's, Gidey in Ethiopia's — and live in our country pages, not here.
The road wing matched them: Abdi Nageeye became the first Dutch winner of the NN Rotterdam Marathon in 41 editions, in a national-record 2:04:56; Yalemzerf Yehualaw won London at 23; and Almaz Ayana won Amsterdam with a course record that stood until a team-mate broke it two years later.
Arm sleeves are removable knit tubes from bicep to wrist that give runners adjustable warmth at cool starts, UPF sun protection, light compression and — worn singly — a sprint signature. They are the most modular piece in the race kit.
Their origin is basketball: Allen Iverson's trainer cut a compression stockinette for his elbow in January 2001, Iverson scored 51 that night, and the sleeve became a league staple before crossing to marathon start lines and single-armed sprinters.
The jobs are plural: warmth without a jacket, sun protection in UPF-rated versions that block around 98% of UV, light compression, and — not to be underrated — identity. A sleeve is the cheapest way a kit says something personal inside a federation uniform.
A pair weighs less than an energy gel, which is exactly why the cold-start calculus favours them.
