I am sharing this with you because I want you to know that you don't necessarily have to do a TON of high mileage weeks in order to reach your goals!
For me, quality helps more than quantity.
Are you a high mileage or low mileage runner?
Being a lower mileage runner with 3-4 rest days per week seems to work decently well with my body. But I know TONS of people who do really well with high mileage training plans, so perhaps that's the key to being a fast marathoner? I'd like to try a higher mileage training plan at some point, so if you're a high-mileage runner, tell me if you think it works and I'm curious to hear how you do it without getting injured.
