Ski Mountaineering (Skimo) Training Zones
Climbing is the event. Use 5-zone heart rate plus vertical ascent rate (Vm/h) to pace sustained climbs and intervals.
Max Heart Rate Calculator
Your maximum heart rate is the highest your heart can beat in all-out effort. Age formulas estimate it: Tanaka gives 208 − 0.7 × age; the classic 220 − age tends to run high. At age 35 that is roughly 184 and 185 bpm, but the real value varies by ±10–12 bpm, so test it to be sure.
Heart Rate Zone Calculator
Your heart-rate zones are percentages of your maximum heart rate: Zone 1 is 50–60%, Zone 2 60–70%, Zone 3 70–80%, Zone 4 80–90% and Zone 5 90–100%. At a max of 185 bpm, Zone 2, the key aerobic-base zone, runs about 111–130 bpm. Spend most easy training in Zones 1–2.
Ski Mountaineering Vertical Calculator
Ski-mountaineering is decided on the climbs, so vertical ascent rate (Vm/h) is the key anchor alongside 5-zone heart rate. VAM is vertical metres divided by hours: climbing 600 m in 30 minutes equals 1,200 m/h. Pace long climbs near 70–95% of test VAM, about 840–1,140 m/h here.
