The IRONMAN 70.3 Switzerland in Rapperswil-Jona is known as one of the most spectator-friendly events across the entire IRONMAN European Tour with its consolidated event area and all locations within a short walking distance. The race boasts a 1.9k swim in the beautiful Upper Lake Zurich and a truncated bike course, which leads athletes along the lake shore and through picturesque villages. On the almost infinite descent from Goldingen back to the lake, athletes can relieve their tired legs, before the course leads them back to Rapperswil-Jona. The concluding half marathon takes the athletes through the medieval part of the city and along the lake shore and features the castle stairs with its 53 steps, famously known as the “Stairway to Heaven”.
