Pick a finish time and OTRI says what it would score, from the course and the time alone: the course is measured every 50 m and costed by gradient, and your speed over that flat-equivalent distance is compared with the fastest anyone has sustained over that much ground. How a score is made. This is a course for trying a target time, not a race page; results are never expected here.
