What racers and reviewers say
- RaceCheck (David M.)Raced 2016 · aggregator · Negative
Regional athlete based in Saudi Arabia who sees it as a convenient local race but not worth long-haul travel. Enjoyed the F1 circuit lap but thought the rest of the ride repetitive along a large highway.
- RaceCheck (Mark L.)Raced 2016 · aggregator · Mixed
First-timer: sheltered lagoon swim, split transition the main drawback, bike enjoyable on closed coned roads but marshalling confusion made some cut 6-8 km (4-5 mi) and a police car knocked him off. Run flat through a sheltered wildlife park with few spectators; homestay made logistics easy.

Visit report: single-site race with choppy swim, flat bike of about 300 m (984 ft) gain on excellent roads, run of repeated loops; strong catering, medals and a welcome banquet. An age-grouper who qualified called the bike phenomenal.
