What's New in RunIntensity
1.1.0
September 26, 2026
Readiness gets two new signals, and hot days finally count. • Illness signal — when your overnight wrist temperature or breathing rate runs above your own baseline, Readiness says Recover and tells you why. Needs an Apple Watch that records them. • Heat — a hot, humid run asks more of you than the same run in cool air. Your Freshness now reflects that, and each workout shows the pace it would have been in cool conditions ("feels like 7:25"). Stress-Adjusted Miles are unchanged, so your weekly totals stay comparable. • Time on your feet — days well past your usual step count now count as easy walking against Freshness, so a 20,000-step travel day no longer looks like a rest day. • Your intensity-coloured route maps now appear on the coach web dashboard, with the same Stress / Pace / Heart rate / Elevation views and a fly-through of the route. Plus the usual round of fixes.
