How does Engine handle different sports?

Engine fuses running, walking, cycling and swimming into one aerobic picture, and leads with the direction (rising, flat or falling) with the 0 to 100 level underneath, because the trend is what you can act on. Pick your main discipline under Settings > Profile so your goal sport is weighted properly; cross-training still counts but is capped so it never overstates goal-specific fitness. After a genuinely hard effort it also shows predicted race times for standard distances.
