Out to the turnaround in Höchst and back. In 2025 the headwind at km 15–20 along Mainzer Landstraße cost the most, and the tailwind home went unused.
Numbers are km markers. North is up.
65 m up, 64 m down, 94–117 m above sea level. 10 m between grid lines.
Computed from the direction the course runs in each kilometre. A kilometre counts as headwind when the wind comes from within 60° of straight ahead, and as tailwind when it comes from within 60° of straight behind. Find the forecast wind direction and read your row.

65 m of climbing and 64 m of descent over 42.195 km, between 94 and 117 m above sea level. Out to the turnaround in Höchst and back. In 2025 the headwind at km 15–20 along Mainzer Landstraße cost the most, and the tailwind home went unused.
It depends on the wind direction on the day. With a wind from the west, the course has a headwind on km 3–4, 9, 14–24, 26–27, 41–42 (42 % of the distance) and a tailwind on km 1, 6, 12, 28–34, 36–38. The table on this page lists all eight directions; the race plan uses the actual forecast hour by hour.
Windsplit shows a forecast from 16 days out, but wind forecasts usually converge in the last three days. Check the evening before and again on race morning: the tool refreshes every 30 minutes, and the confidence line shows whether the models agree.
Yes. Replay reads the activity from Strava or a GPX/FIT file, fetches the weather that was recorded along the route, and shows the wind, hill and heat cost per kilometre, plus an adjusted pace in still air. If you planned the race in Windsplit on the same device, it compares the prediction with the result.
