2 laps in total 3,8km

CHALLENGEALMERE-AMSTERDAM starts with two swim laps in the Weerwater. The start is next to the Kunstlinie (Theater) on the Esplanade in Almere Stad. You will swim counterclockwise. The first transition – from swim to bike – takes place in the Lumierepark, where you will exit the water.

94% of the participants think the swim course is (very) good! 


A 2-lap structure (90.7km per lap)

The bike course of the CHALLENGEALMERE-AMSTERDAM Long Distance triathlon has a 2-lap structure. A connecting road takes you alongside the lake Weerwater and through the woods of Almere Haven. Once arrived at the dike, the first lap starts in westward direction. For about 45 km (until you’ve reached Flevoland’s capital Lelystad) there will be water on you’re left-hand side. On clear days, this passage will provide a spectacular view of Amsterdam at the other side of the IJmeer. At your right side you will pass the Oostvaardersplassen, a wildlife reserve containing numerous animal species. At the roundabout in Lelystad you turn right to cross the polder while cruising on the reclaimed land below sea-level. From there it’s all about straight roads, wind, and the elements in the polder. A bridge will take you to the Zeewolde territory.

After reaching the dike again there’s an important choice to make. Participants of the Middle Distance triathlon will turn right towards Transition 2, as do participants in the Challenge Long Distance after lap 2. After lap one the Challenge Long Distance athletes go straight on to a second lap of dike and polder.

After finishing lap 2 and returning to Almere, also the second transition will take place in the Lumierepark Almere Stad.

4 laps of 10.1km (plus two times 900 meter to start and finish the marathon)

From the Lumierepark, you start your running course through the modern architecture of the city centre. The centre of attention is the green area around the Weerwater, the lake in the middle of Almere that once was a sea. The running course consists of a 900-meter lap to kick off, then four 10.1 km laps to be completed before a final 900 meter stretch to finish your race on the Esplanade.

94% of the participants say the run course is (very) good!
