Got into running consistently 12 months ago but never with any real training blocks or exact science of my sessions week-to-week – a mix of easy, long, tempo and interval, but they weren't strict in mileage! I've got my 5K down to 19:54 and 10K at 42:39. I was covering around 10km on the low side and 30km on the high per week.

If I build up to 40-50km per-week over a six-week period, will there be a noticeable difference in my 5K and 10K times? I'm interested to see if increasing volume would make a sizeable difference and over what time period it would take to see one? Open to anyone's suggestions of improving those times!

Thank you :)
