IRONMAN Jonkoping
Jönköping sits at the southern tip of Lake Vättern, and its 70.3 uses the smaller lake in town: 1,900 m in Munksjön, then 90 km through the Småland countryside and 21.1 km back through the centre of the city.
The bike rolls rather than climbs, on quiet forest and farm roads with good surfaces, and it is quick if the wind stays off the open sections near the water.
Two things a first-time visitor should plan for. Swedish lake water in July is comfortable rather than warm, and daylight at this latitude runs long into the evening, which is useful for late-finishing athletes and unhelpful for sleeping the night before.
The town-centre run is the strength of the race. It is flat, spectator-heavy, and close enough to transition that anyone supporting you can see the finish, the swim exit, and most of the run without moving far.
