Advice from anyone is welcome.
I am a 29 year old female who started running a few years ago. I finally have the time and energy to be serious about running (serious for me means meeting certain time goals, improving my pace, ect.). I have made a lot of improvement with consistent speed work and tempo but my weakness has generally been inconsistent base mileage. I generally run 20-25 miles per week. My goal is to improve from a 23:00 min 5k to a 21 min 5k.
Basically, what mileage would I aim to build up to in that attempt. I know 2 minutes in the 5k is a pretty significant jump and I'm not expecting this to be a short term goal by any means- Any advice is welcome.
Also- I am 5'6 and 119-120 lbs so I am in pretty good shape- I have felt the best physically at 116-117 so while I'm a little over where I feel I race the best it's not like I have 10+ lbs to lose.
Thanks!
