I can run 10k in 1hr. I'm 45 and a bit fat and not very motivated. I have to sign myself up to 10k races otherwise I don't do anything. I ran three in December but done nothing since.
Presumably aiming to run 10k in 50 minutes is likely to have more benefit than aiming to increase my distance to run 20k? I reckon I could plod round 20k in 2hrs without much effort.
Yeah, I'd think so.
But part of getting the 10k down to 50 minutes will include some 1.5hr 15k runs. It's easier to run faster for a short time when you're comfortable running slower for longer.
Sign up to the races to give you the targets to aim at, and mix up short fast training with long slow.
