at the finish

Real forecast data along the RMB Ultra-trail Cape Town route, re-timed at a 6 km/h example pace. In the app, the whole timeline re-times to your pace. RMB Ultra-trail Cape Town is an independent preview: the forecast is real, and the route, start time and checkpoints around it are RaceWell's own reconstruction, not the organiser's entry.

Below 0 the wind pushes you along; above 0 it pushes back.

tailwind headwindafter dark

The profile is painted with the wind at the hour you’ll pass each point — deeper colour, stronger wind. Notches mark the checkpoints.

Wind at your position on the route — arrows point where the wind blows, longer means stronger. Green dots are checkpoints.

Fuelling that reads the forecast

Published intake ranges, held against the conditions on each leg of the race. The sodium range appears only where the readings meet the scope it was published for — and the page says which condition put it there.

Per hour, held against the conditions on this race's legs.

Carbohydrate 30–50 g/h
Fluid 450–750 mL/h
Sodium 300–600 mg/h

Sodium appears because this plan is above 60 % humidity in the six-hour block covering it — the scope its source sets, which is hot or humid. Outside that scope the row is simply absent.

Published intake ranges held against this plan — not a prescription. What to take is the racer's own call.

The kit list the forecast decides

Many races set compulsory kit by conditions. RaceWell shows which level a forecast points at, and what that level adds to the list, while there is still time to find the missing item.

RMB Ultra-trail Cape Town

18 compulsory items, and the list never moves.

RMB Ultra-trail Cape Town will never change or downgrade this list based on weather forecasts.

Where an organiser does vary the list by conditions, RaceWell shows you which level the forecast is pointing at before race week.

Your pace, not a pace

Say how the day is going and the whole plan re-times in front of you — every ETA, every checkpoint, every forecast reading. The cutoff buffer moves with it.

At the 6 km/h example pace this page states — the app re-times all of it to yours.

20:10 at the line · 27 h 10 moving · 163 km

Inside the cutoff

RMB Ultra-trail Cape Town's published final cutoff is 14:00. At this pace you finish 20:10 — 17 h 50 inside it.
