Etape Caledonia: Course, Elevation & Route Profile

Course & Elevation

The day opens with two small ramps at kilometre 5 and 9 and then turns serious for the first time at kilometre 22: a little over four kilometres at 5.3 per cent average with pitches to eleven, up to Trinafour, some 220 metres of gain in one go. Over the top the road drops back into the valley at Kinloch Rannoch, and that is where the real character of this loop begins.

From kilometre 34 to kilometre 76 the elevation trace is practically a straight line at around 210 metres. That is forty kilometres around Loch Rannoch, out to the western end at Bridge of Gaur where the road brushes the edge of Rannoch Moor and one of the emptiest corners of Britain, and back along the narrow south-shore road. Forty flat kilometres sound like recovery. They only are in a group.

At kilometre 77 comes the climb everyone asks about: a little over two kilometres at 6.4 per cent with a ramp to twelve, onto the flank of Schiehallion, topping out around 366 metres shortly before kilometre 90. After that the course falls in one run to a little over 110 metres and rolls home through Coshieville and Aberfeldy as a valley run to Pitlochry, with two last short ramps at kilometre 128 and 131. It is ridden in May on fully closed public roads, and because a sweep bus follows the field at 21 km/h with the roads reopening behind it, the course carries hard intermediate cut-offs.

Pacing Strategy

The course breaks into three parts and only the third decides it. The climb to Trinafour at kilometre 22 arrives so early that it rides itself: it is long enough to overcook, and taken in the red it buys you almost nothing. Ride it at your own rhythm and accept that a group may be gone at the top.

The forty kilometres around Loch Rannoch are the day's actual tactical problem. On the flat the group makes the difference, not your form: riding the open lochside into a headwind on your own costs more time over that distance than the whole Schiehallion climb. So make a point of latching on at the bottom of the Trinafour descent, share the work sensibly, and eat where the eating is easy.

The trap sits at kilometre 77. The Schiehallion climb only lasts six to ten minutes, but it comes after four to five hours and straight out of group pace. Ride the last kilometres before it on the front and you will lose more there than the turns were worth. Let the group go in good time, climb it evenly, and keep something for the forty kilometres that follow: they fall on balance, but they are not flat.

Training plan for Etape Caledonia: 12-week build

For age-group riders the 85 miles typically take five to seven hours. The demand is unusual for a course with nearly 1,400 metres of climbing: over forty per cent of it sits in the flat band, and the single longest continuous section is a forty-kilometre plain. What it asks for above all is the ability to ride many hours just under endurance threshold at group pace, broken by two longer climbs.

The race-deciding section is the Schiehallion climb at roughly four fifths of your riding time. Train that exact combination: long rides of five hours and more with the one hard climb deliberately placed right at the end, plus threshold intervals of six to ten minutes done at the finish of a long session rather than the start. The Trinafour climb asks for the same quality in a longer form, around twenty minutes.

The second theme is riding flat in wind. Loch Rannoch is open ground, May in Highland Perthshire regularly brings a firm westerly, and the south-shore road is narrow. Ride long headwind sections deliberately through the build, and practise holding steady power rather than steady speed, and sitting close and calm in a group.

Then there are the conditions of the day itself. The start is at half past six in country that can be near freezing at dawn in early May and mild by midday, so clothing strategy and six hours of fuelling belong in the preparation. And because the sweep bus runs at 21 km/h and there are time limits at the route split and at the feed stations, a durable average speed over the full distance is not a side goal but the entry condition.
