Finish-time, pacing & training calculators for fitness races.

Built for the standard hybrid Hyrox fitness race format (8 × 1km runs + 8 stations). Use these tools to estimate a finish time, build a pacing plan, set training paces, and identify station bottlenecks.

Core calculators

US-first • worldwide athletes • demo logic for now

1) Finish Time Predictor (Demo)

Estimate a finish time from your 5K time and “station factor”. Units toggle affects pace display.

Result: Enter your 5K time to estimate a finish time.
Next upgrade: station-by-station split table + doubles/relay modes.

2) Pacing Plan Builder (Demo)

Input a target time to get suggested average run pace + station budget.

Result: Add a target time to generate a pacing outline.
Next upgrade: station-specific target splits + compromised running pacing.

3) Training Zones (Simple)

Estimate training paces from a 5K time (rough guide). Upgrade to HR zones later.

Result: Enter a 5K time to see suggested paces.
Next upgrade: threshold test input + heart-rate zone estimates.

4) Station Benchmark Check (Quick)

Self-assess key stations to find a likely bottleneck and what to train next.

Result: Add a row time and wall balls count to get a quick focus.
Next upgrade: add ski time, farmers carry, and lunge capacity for a fuller profile.

What most racers actually need

We keep this simple: shoes that handle running + stations, something to track training, a couple of strength basics, and recovery/fuel staples. When we add affiliates later, we’ll keep it tight and transparent.

Country set to: US

Shoes / Trainers

Prioritize stability + grip while still feeling good on runs.

Watch / Heart-rate strap

Helps with pacing, intervals, and consistent training zones.

Kettlebells / Dumbbells

Great for lunges, carries, and strength endurance.

Sled substitutes

Sandbags, sleds, and heavy pushes to build the right engine.

Recovery

Mobility kit + foam roller (and massage gun if you want).

Fuel & hydration

Electrolytes, carbs for long sessions, and protein basics.

FAQ

Short answers for SEO + trust

Is this site official?

No. This is an independent tools site for fitness-race athletes. See the disclaimer below.

Why does the format use km?

The standard fitness race format is commonly structured in 1km run segments. You can toggle miles for pace display.

Are these predictions accurate?

They’re estimates (demo model). Accuracy improves when we add station proficiency and past split inputs.

Can I use this if I’m a beginner?

Yes. Start with the finish-time estimate, then use pacing and zones to guide training.
