  • Sondre Amdahl

    Raced 2015 · Sondre Amdahl

    Tone: Positive

    Amdahl finished second in the 2015 edition and praises the volunteers, organization and varied coastal-to-urban views. He describes late climbing and a chilly wait after arriving early by bus. This invited elite perspective predates the current course and cannot establish today's aid experience for slower runners.

  • Will Hayward

    Raced 2013 · Will's Random Race Reports

    Tone: Mixed

    In a retrospective passage, Hayward describes starting the 2013 Hong Kong 100 too aggressively, becoming sick and weak, then recovering after a break to finish in 16:41. His account supports caution about the hillier second half. It provides little detail about race services and does not describe the current course.
