EASY DOES IT
Exercising outdoors can be a bit of a shock to the system, so give yourself time. It can take up to 14 days for your body to adjust to temperature changes, which include your body adapting to reduce heart rate and core body temperature, and increasing your sweat rate. Therefore, avoid asking too much of your body too soon. When making the transition from indoor to outdoor workouts, start off with relatively short bouts of exercise and go easier on the intensity – no setting personal bests.
THE RIGHT TIME OF DAY
Avoid training at midday when it is warmest, instead try to early or late in the day. The sun’s intensity is at it strongest between 10 a.m. and 4 p.m. Early morning tends to be the coolest time of the day to exercise outdoors, as the roads have not yet heated up from the sun. If you can’t avoid exercising in the middle of the day, look for a shady workout location or running route.
