    One enthusiastic age-group report plus local press. This is an inaugural year with no broad sample, though the winner says he will return. · Low confidence

  • OrganizationWell run4.0

    One athlete says logistics ran without a hitch, with buses to the lake. A steep T1 and a backed-up bike turnaround were small flaws. · Low confidence

  • First timer friendlyDemanding2.2

    Altitude near 2,100 m (6,900 ft), a punchy run and only about 53% finishing (746 of 1,390) make this hard for a first 70.3. · Low confidence
