Ultra Marathon training plans, built for your goal
Ultras are won or lost by how well you manage fatigue over 40, 80 or 160km, not by how fast you can run a single kilometre — training has to prioritise time-on-feet and fuelling as much as pace. SportBlox builds your ultra marathon training plan around your goal distance, terrain and current base.
Who it's for
First ultra beyond marathon distance
A gradual time-on-feet build with back-to-back long runs that teach your body to run tired.
Stepping up in distance
Progressive weekend doubles and vert work for runners moving from 50K to 50-mile or 100K distances.
Technical or mountain terrain
Extra downhill-specific strength and vert-focused long runs for hilly or technical race courses.
A week of ultra marathon training
Example: a runner building toward a 50-mile trail race with rolling terrain. Your own plan is built around your event, level and schedule.
How SportBlox personalises it
Your goal & event date
Sessions build toward the specific goal and date you set, with a taper if you're racing or competing.
Your skill level
Volume and intensity scale to where you actually are, from Inexperienced to Professional.
Your stated weaknesses
Tell SportBlox about things like downhill quad fatigue, eating and drinking while running, pacing the first third too fast and the plan weights sessions toward fixing them.
Your schedule
The plan fits the days and time you say you have — not an idealised training week.
Works with Strava
Connect Strava and your logged sessions feed back into pacing and progression.
Ultra Marathon training plan FAQ
How does back-to-back long run training work?
Saturday and Sunday runs stack fatigue the way race day does, teaching your legs to hold form when tired without the recovery cost of one huge single run.
Does it cover fuelling strategy?
It builds in nutrition and hydration practice during long runs and flags it as a rehearsal for race-day fuelling, though specific product choices are yours.
Can it handle a hilly or mountainous course?
Yes — tell it your race's elevation profile and vert-specific climbing and downhill strength work is prioritised.
Is this suitable for a first ultra?
Yes, set your goal distance and skill level and the plan builds time-on-feet conservatively rather than chasing pace.
Does it work with Strava for elevation data?
Yes, connect Strava and logged runs including elevation feed back into progression.
