MTC Thames Challenge Stage 3 (Windsor Ultra)
Calculated from 76 km alone — the organiser has not published an elevation profile. Read 3.8 as a floor, not a verdict.
What the course asks
DUV results for the 2025 edition (184mi/4stages) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
Typical conditions, August
Regional 2001-2020 average for August — NASA POWER, grid elevation 87 m. Not a forecast.
