Outdoor Standards & Adventure Calculators
Outdoor training gets vague fast unless you measure something real. This hub pulls together the core FITTUX outdoor tools and calculators so you can plan better routes, estimate effort, and understand what a hike or cold-water dip is actually costing you.
Distance alone doesn’t explain outdoors. Elevation, terrain, wind and cold exposure can turn a “nice walk” into a big session. Use these as rough guides to stay consistent, not to chase perfect numbers.

Use this hiking calories calculator to estimate calories burned while hiking based on your bodyweight, hike duration, elevation gain and pack weight. Compare hiking routes, calculate energy expenditure on uphill and downhill terrain, and see how many calories a hike is likely to burn before you set off.
Go to Hiking CalculatorWild Swimming Calories Calculator (UK Water Temps)
Use this open-water swimming calories calculator to estimate calories burned during wild swimming, sea swimming and cold-water swimming. Factor in water temperature, swim duration and bodyweight to calculate realistic energy expenditure in typical UK rivers, lakes and coastal waters.

Outdoors is messy in the best way. Two routes with the same distance can feel completely different depending on climb, footing, weather and how hard you push. Use these tools as planning anchors — a way to compare sessions and make smarter choices — not as exact measurements.
If you’re building fitness, the win is repeatability. Pick something you can do weekly, track a few consistent sessions, then progress by adding time, elevation or a little load. That’s how outdoors stops being “random effort” and becomes training.
