Skip to main content Running shoe reviews, GPS watch tests and 16+ free science-based calculators — built on a published methodology. Every pick names its trade-off. Zero paid placements.
Six working tools, not six landing pages. Each one asks what it needs to know, shows the reasoning, and sends you somewhere specific.
01 Nine questions on fit, surface, mileage and injury history. It returns shoes that suit you, not the shoes with the biggest affiliate payout.
Matched archetype: Stable neutral daily trainer (e.g. Brooks Ghost Max 3 / ASICS Cumulus 26)
02 TDEE, macros, pace, VDOT, heart-rate zones. Every calculator prints the exact formula it used, so you can check the maths yourself.
03 GPS accuracy, real battery life and wrist heart-rate reliability, ranked against the budget you actually have.
04 Zone 2, heart-rate zones, and marathon build-ups explained without the mysticism.
05 A free eight-week block that adapts to the days and equipment you actually have.
06 What the evidence supports, what it does not, and which supplements you can skip.
Most “what runner are you” quizzes hand back a personality label. This one hands back a heart-rate band, a shoe category, a weekly structure and a four-week mileage ceiling — calculated from published formulas, with the formulas named.
This sets your estimated maximum heart rate using the Tanaka formula: 208 − (0.7 × age).
Length, width, arch under load, heel lock. Two runners with the same size often need different shoes. We measure late in the day, both feet, thumbnail of space.
Soft ≠ better. We test rebound, fatigue over 20km, and whether the foam collapses under heavier loads. Comfort is a function of your weight, pace and weekly volume.
We log every mile. Outsole abrasion, midsole compression lines, upper deformation. A 300-mile shoe that dies at 180 isn’t value — it’s a warranty claim.
A €140 shoe that lasts 500 miles beats a €90 shoe that dies at 250. We compute cost-per-mile, not RRP. Budget picks must clear the same bar as flagships.
Every verdict ends with the trade-off and the “skip if” line. If a shoe encourages bad mechanics for your foot, that’s a safety call — and we say so plainly.
Mud, scree, wet rock, treadmill hum. Every verdict below survived real miles before it survived editing.
Drag the handle horizontally or click the preset modes. Most buying guides rank by affiliate payout. Ours rank by biomechanical use case.
A live slice of the calculator library. Drag the sliders — the gauge updates instantly, and the formula is printed below.
Calculate your exact Total Daily Energy Expenditure via Mifflin-St Jeor to anchor training nutrition, fat loss, or endurance refueling.
Convert min/km to min/mile and preview projected finish times across standard race distances.
Estimate your functional aerobic capacity (VO2 Max equivalent) from a recent 5K test time.
Calculate your 5 aerobic training zones using the Karvonen Heart Rate Reserve formula for Zone 2 endurance base building.
Five zones from recovery to VO2 max, based on your estimated maximum heart rate (220 minus age). Drag to match your age — every bar updates live.
Most of your weekly volume belongs in Z2 — conversational, aerobic, sustainable. Hard sessions live in Z4–Z5. Use these ranges to keep easy days easy and hard days hard.
Comprehensive categorization across daily miles, speedwork, and long-run recovery.
Mountain scree and technical descent durability tested across 150 rugged trail miles.
Premium cushioning and joint preservation evaluated over high-mileage blocks.
Multi-band GPS accuracy benchmarks and battery metrics under full offline mapping loads.
What to buy, what to skip, and when spending more pays off.
Modern supercritical foams that strengthen natural foot architecture without plates.
No sign-up, no email wall. Each takes under two minutes and links straight to the guide behind the recommendation.
Nine questions on fit, surface, mileage and injury history. Returns shoes that suit your foot — not this season’s marketing push.
Find my shoe → Rank GPS accuracy, battery life and training features against your budget — then see which watches genuinely clear the bar.
Match my watch → Sixteen-plus calculators for TDEE, BMR, macros, body fat, pace and heart-rate zones — each showing the formula it uses.
Open calculators → A structured body-recomposition plan built on progressive overload, realistic recovery and training you will actually finish.
Build my plan → Start with fit, not features. Measure both feet late in the day, leave a thumbnail of space, check width. Then match the shoe to surface and weekly mileage.
Full guide →300–500 miles — but feel beats mileage. Replace when the midsole stops rebounding or new aches appear in shins, knees or hips.
When to retire a shoe →Almost certainly not for everyday running. Carbon is for race-day efficiency at faster paces; it rides firm on easy miles and costs more.
Best plate-free →TDEE minus 300–500, protein high. Aggressive deficits damage performance and recovery before they speed fat loss.
TDEE guide →Every review follows criteria we publish openly, so you can judge the judgement.
Read the methodology →Each recommendation names what the product is worse at. Nothing scores well on everything.
How we score →No fake live prices, no invented star ratings, no testing we did not do. Manufacturer specs labelled as such.
Data policy →No paid placements and no brand approval over verdicts. Edited by Alexios Papaioannou.
