Question: How many miles should I be increasing weekly to train for a half-marathon?
Answer: It depends on your training schedule and how many weeks you have to train. If you have adequate time to train you should ideally increase your long run day mileage by 1 mile each week until you reach 12-13 miles. I typically start with 3 miles and add 1 mile each week until I reach 13 miles.
