Pack this
- Wetsuit (likely legal in ~18°C Øresund water) + anti-chafe stick

What you should know
- Mandatory athlete check-in and mandatory bike + blue/red bag drop the day before — no race-morning bike racking.
- Wetsuit legality is decided race morning based on water temp; have a non-wetsuit plan if Øresund exceeds 24.5°C.
- Drafting is strictly enforced on the bike — keep 12m gap; penalties served in the next penalty tent.
- Mid-August in Copenhagen can swing from 15°C rain to 25°C sun; pack arm warmers and a light rain layer for T1.
