My sister’s boyfriend runs multiple half marathons and shorter races throughout each year. Living in the Las Vegas desert, where temperatures top 100 degrees Fahrenheit through most of the year, long runs are impractical.
You can’t run outside in such extreme heat for more than half an hour, not even in the morning (as temperatures don’t drop below 80 degrees many days, and that’s already rather hot for running). And running 10+ miles on a treadmill, if the gym will even allow it, isn’t psychologically feasible for most.
