The UCI Road World Championships begin Sunday with a doubleheader of elite competitions as the women kick off proceedings with a 29.9km individual time trial from Gossau to Zürich, followed by the men taking on a 46.1km test against the clock.
Sunday's action begins with 70 elite women gathered in Gossau, located in the northeastern corner of Switzerland near the border of Liechtenstein.
There is 327 metres of elevation gain largely in the first half of the route which passes through the foothills of the Pfannenstiel. The first uphill winds through Oetwil am See for 2.6km, the gradient averaging 4.5%. Shortly afterwards comes a smaller rise of 1.4km, which leads to a steep 1km descent featuring pitches of 10-12%.
Once at the bottom of the downhill, a right-hand turn leads to the flat section on the eastern shore of Lake Zurich for 12km to the finish line at Sechseläutenplatz in Zürich.
There are time checks at the top of the first climb, with a little more than 10km covered, and another 10km later once on the flat stretch along Lake Zurich after passing Herrliberg with 9.4km to go.
