Hi everyone,

I have a 25km mountain race coming up at the end of February and I anticipate going very hard for 2.5-3 hours. It’s likely that the majority of this race will be above my aerobic threshold. I normally run ultras and have never run or trained for a shorter distance race. I would welcome any insight in how I can adapt UA methodology to a shorter race. How do I train for a high intensity race without undermining my AeT?

This is what I’m thinking so far:
-normal 8 week base training period under AeT with ME workouts
-introduce both short hill sprints and longer duration Z3 hill climbs after base period
-limit Z3 to 10% of training time per week

For context, here is my training background:
-have run 10 ultra distances over 3 years (both races and adventures) primarily using Big Vert training plan
-all races have been between 50-60km
-training around 400 hours/year

Looking forward to your feedback. Thanks in advance!
