If you fancy a run in the desert, the Al Wathba Cycle Track is a good destination. Amidst the dunes and dirt/sand roads, there’s a 30 km long paved path that is popular for cycling. Running here is also possible…but you should be mindful of cyclists! The area is about a 45 minute drive from Abu Dhabi. There are marked loops of 8, 16, 20, 22, and 30 km. The are restrooms, changing facilities, and bike rentals.
One can also run in the desert surroundings here. There are numerous roads and paths, but they can be sandy and the surface more challenging for running.
Notes: Most scenic at sunrise or sunset. Also this track is lit at night! Note also that this area is very exposed — be attentive to the sun and heat.
