Half Marathon Strategy
The half marathon is a challenging endurance event. Start conservatively, running the first 5K slightly slower than goal pace. Settle into rhythm through the middle miles, then assess how you feel at 15K. If you have energy, gradually increase pace to the finish. Proper fueling during the race is important.
