run = 2025 · bike slower than all three because of the 152 cap

The 5:50 was too slow next to three finishes. You have never ridden a 70.3 bike slower than 3:01, and never run one slower than 2:01. Aerobic running is back to 2025 (EF 0.0211 vs 0.0213; 5:22 @ 152 vs 5:18). The bike cap (152 vs 162–172 in those races) is why this is not 5:21. Vitruvian is flatter than both Weymouths (5.5 vs 11 m/km) and not Valencia. Range 5:32–5:52. *2025 swim missing from the file — 33 min added, per No. 6. 2023 swim unlogged — 35 min reconstructed from bike start 07:46.

Bike

Same kind of Dorset road, ~12 m/km. Efficiency +11% on those climbs. No power meter — this is speed at a pulse.
