Runna introduces a new coaching feature, “Adapt for Heat,” available to subscribers starting today. The feature automatically adjusts a runner’s workout targets based on current local weather conditions, specifically heat and humidity. According to reporting, if conditions are hotter or more humid where the user is running, the app changes the workout accordingly rather than keeping pace targets fixed. The implementation centers on adapting training paces to account for how those environmental factors can affect performance and exertion. Both outlets describe the same core capability: the Runna app uses localized temperature and humidity information to modify workout pacing goals during training. The updates are positioned as an automatic adjustment within the existing Runna coaching experience, with users opting in through the feature as part of their subscription. No additional technical details, rollout timing beyond “starting today,” or limitations on supported devices were included in the provided summaries.
