Thanks for all your work - I love the app. Paid subscription.
My indoor gym performance is top rated. As soon as I walk or run outside (i do it for hours) - it DECREASES (!) my short and long term fitness! I am 10 years younger than my age per Athlytic metrics. So what is happening? SUMMER in FLORIDA. Heat, humidity - i call it 90- 90 weather -- 90s in temperature and 90s in humidity. No normal human can walk / run for 1 hour in afternoon in this weather and feel like it is indoor walk or run on a treadmill.

Please take weather in account. This data are available somehow via phone / watch / app ecosystem. It is very biased not to take in account weather and other conditions. For example look at this:

Thanks!

Feature request: account for environmental load in Fitness

Heat and humidity reduce evaporative cooling, increase cardiovascular and thermoregulatory strain, lower sustainable workload, and with repeated exposure produce real heat-acclimation adaptations. A lower pace or lower mechanical workload therefore does not mean a proportionally smaller training stimulus.

Athlytic’s TRIMPexp already captures some of this indirectly through HR, but the environment itself is absent. Workout time and location make historical weather available.

Could Training Load incorporate an environmental/heat-load component, or at minimum use it when interpreting changes in Short- and Long-Term Fitness?

For outdoor endurance work, 90°F humid Florida and an air-conditioned room should not be treated as equivalent training environments.
