I only got below 25:00 minutes once during a Parkrun back at the start of 2019 and havnt been able to do it since. Before Covid, I was doing track work with a running club every 2 weeks but my speed just doesn’t seem to improve.
I run 25 – 30 miles a week and I am trying to build an aerobic base. I do the majority of my running, including the long run, at 10 min mile pace but really struggle to go faster. Anything near to 8 minute mile then I really struggle to maintain.
Im not sure what else to do. Any help would be greatly appreciated.
