Starting in the village of Marlens. The route initially follows 5 Km of the wonderful dual lane cycle-way that stretches for 30 Km between Annecy & Ugine. From Ugine the climb of the Col de la Forclaz 'Ugine' begins (there is another one nearby). This 5 Km climb certainly gets the lungs burning kicking up to 14% at times. Descending the other side the route picks up the D925 towards Beaufort. After 8 Km the climb of the Col des Saises begins..The gradient is really nice as the road winds it's way to the summit, with views of Mt Blanc in the distance and 14 Km later you arrive in the ski resort of Saises and ready for a descent, which is quick and quite open, although the is a small rise part way down. On reaching Flumet the run into the Col des Aravis begins although initially the road undulates following the river up a gorge and it only really steepens up switchbacks for the last 5 Km. The route descends towards La Clusaz before taking a left and taking the short climb up to the Col de la Croix Fry. The decent however goes on for some 8 Km to pick up the D12 at Chamossiere. The road climbs steadily from here and descends to pick up the final climb of the day the Col de l'Epine. Initially the climbing feels quite tough before a short descent and an easing in the gradient all the way to the summit....The descent....well it's just great, all the way to the finish in Marlens
