Course intel
90 km around the north and west shores of Lake Coeur d'Alene; the official description calls it challenging outright: about 793 m of elevation gain, wide roads, good sightlines. You pass the hot corner near transition three times. Late June in Idaho warms up fast during the day; with an early start, the first half is cool and the second half is hot.
