Source: 2023 IRONMAN Copenhagen Athlete Guide (opens in a new tab) (retrieved 2026-07-15). All cutoffs are elapsed time from your individual start chip, not the fixed race clock. These are the official published cutoffs as of 2026-07-15; always verify in the current athlete guide before racing, as organisers can revise them each season.

Course and Start Notes
Sea swim off Amager Strand, fast flat bike, and a city-centre run. The bike (9:30) and overall (15:45) cutoffs are tighter than the standard full-distance gates, so pace the bike accordingly.

How this calculator works
Cutoff gates were read verbatim from the official 2023 IRONMAN Copenhagen Athlete Guide and are elapsed time from each athlete's individual start chip. The calculator compares your projected swim, bike and run splits, plus transitions, against those gates.
Assumptions
- • Cutoff gates are elapsed time from individual start chip time
- • Standard published race distances for the format
- • Typical clock times assume a 07:00 individual start
Limitations
- • Cutoffs can be revised each season; confirm in the current athlete guide
- • Intermediate time-of-day checkpoints (race logistics) are not modeled per-athlete
Who this is for
- • Athletes registered for Ironman Copenhagen planning their pacing
- • Athletes comparing their projected splits to the official gates
- • Coaches building a race-day plan around the actual cutoffs
Who this is not for
- • Athletes racing a different event (each race publishes its own cutoffs)
- • Anyone relying on a fixed race clock rather than individual start time
