1 m of climb per km — a flat course, run end to end.
Course, cutoffs and race-day guide
Only 9 weeks before it, where your build needs 13.5 (the generic figure is 16).
What would change this: if you have raced this distance before, say so under “your running” — an experienced runner needs a shorter build than the generic one; or a higher current weekly volume shortens the build this race needs; or a shorter distance at the same event, or a later edition.
