What energy system you use from the time you sit down to put your running shoes on until the time you lie back relaxing after finishing a 10k fun run?

During a 10k fun run, your body primarily relies on the aerobic energy system. Initially, as you sit down to put on your shoes, your body uses stored ATP and creatine phosphate for quick energy. Once you start running, your body shifts to aerobic metabolism, utilizing glycogen and fat stores to sustain energy over the duration of the run. After finishing, your body continues to use aerobic pathways for recovery and replenishing energy stores.
