Hagos Gebrhiwet, with an Olympic 5,000m bronze and a world 5K road title, will run his first marathon in Sydney on Aug. 30. Gebrhiwet has never raced beyond the half-marathon. His debut is highly anticipated but not favored.

Sydney's marathon field includes Alphonce Simbu and Peres Jepchirchir, with Sisay Lemma's 2:01:48 best being the quickest. Gebrhiwet, turning 32 before the race, is the most interesting name due to his unknown marathon potential. Read more culture coverage.

Transitioning from track to marathon has varied results. Gebrhiwet's half-marathon best of 57:41 suggests he may handle the marathon well. However, Sydney's hilly course may affect his debut time, unlike flat, record-eligible courses. Related: Max Jolliffe Sets New Badwater 135 Record, Carmen Maria Perez Close Behind.
