Your actual 5K pace is a better anchor than a guessed race target.
Free ENGN race tool
Your 5K pace is not your HYROX pace. Enter a recent time trial and get one realistic average pace to target across all eight runs.
We will turn your 5K into one realistic average pace for all eight race runs.
Average run pace to aim for
—Aim to average this across all eight 1 km runs. Individual kilometres can move around it as the stations and course take effect.
Why this works
A hard 5K gives us your current pace. The calculator then adds a clear fatigue allowance based on your race format and how strongly you handle the stations.
Your actual 5K pace is a better anchor than a guessed race target.
Singles adds 20, 30 or 40 seconds per kilometre for strong, balanced or developing station athletes. Doubles uses 10 seconds less because the work is shared.
Use one clear average across all eight runs instead of chasing a different split after every station.
A pace is the start
ENGN turns your race, schedule and equipment into a complete hybrid plan—then adapts it around the training you actually do.

Good to know
No. It estimates your running pace between stations. Total race time also depends on station speed, Roxzone time, course layout and conditions.
A 5K is uninterrupted running. In a HYROX race, every kilometre follows or precedes a work station, so sustainable pace needs an allowance for accumulated fatigue.
No. Treat the result as your average across all eight runs. Some kilometres will be a little faster or slower depending on the station, course and conditions.
