Javelina Jundred 100K

12 m of climb per km — rolling; you will run almost all of it.

Course, cutoffs and race-day guide

Only 4 weeks before it, where your build needs 15 (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.

The 16 weeks before it — a full build Not enough
2 wk building for this race
15 wk is a full build for you (shorter than the generic 16 weeks because you already run comfortably above the 35 km this distance assumes)

What you could change

In the order most runners prefer: keep the trip if you can, drop the race last.

  • change distance Take a shorter distance at the same event as Javelina Jundred 100K. It keeps the trip and the entry, and a shorter race costs less recovery while transferring nearly as much preparation.
  • move or replace Look for a similar race later in the window, so Javelina Jundred 100K's preparation has the weeks it needs. Find alternatives →
  • drop Leave Javelina Jundred 100K for next season.

One coherent season: each demanding race gets its own build, taper and recovery; shorter races are placed inside a build. Recovery spacing and carry-over are reviewed product conventions calibrated against our reference plans, not physiological measurements. Planning guidance from course facts and your stated training — not medical or coaching advice. Recovery spacing, how much preparation carries over, and how many climbing weeks a course asks for are our own reviewed conventions — inspectable, and not measurements of your physiology.
