265. Can Anyone Run a Sub 3 Marathon With The Right Training & Consistency?

If VDOT says I should run 8:00 pace for a marathon pace but I plan to run 9:00 pace, when do I practice/switch to running 9:00 pace in training?

If my goal is to run a faster marathon (I am a new-ish runner_ would you recommend doing shorter races during the spring OR focus on building mileage/base and long runs. I am currently running 25 miles per week and ran my first marathon in 2019 but not since

Do you believe sub 3 is achievable for most runners?
