10k and 5k differencies

18:20 min - 18:40 min

The range is greater. An undertrained high schooler could run 17:30. A well trained runnermay only run 19 minutes.

one very common method for estimating your 10k time from your 5k time is:

10k time = 2 x 5k time, plus 1 minute

from this, we can back estimate your 5k time as around 19:00

cheers.

Not sure "under-trained" is the correct word, but the concept is correct. I am an 800/1500 guy who is way past my prime. I can just dip under 40 min in a 10 km but also run under 18 for a 5k. I can also run sub 5 min mile, so you can see that the shorter the distance, the better I race. I wouldn't say I am under-trained at all. Just not a long distance runner.

Complete BS. This isn't even close to accounting for type of runner and workouts. Your book learning is theoretic only, cottensh!t.

Definitely under 18:30 min. 10k is difficult to run. 8k is easier to predict from 5k. Just run 3:40 from the beginning. Even if u end up with a positive split. You should hold the pace.

Speculative questions based on limited information like the OP posed can be answered theoretically at best. Cotton shirt's projection lines up exactly with what Jack Daniels's VDOT would predict. Until the OP feels like supplying more information, that's as much as anyone can say.

Calm down, 5k time x 2 + 1 minute is a common 10k prediction formula. Is it off a bit? Yes, nothing is perfect.

This only really stands true for well trained runners. I have ran less than 15 miles each week for training and my 5k is 19:07 vs 43:30 for a 10k

One is 100% longer than the other.

One is 50% shorter than the other.

You're welcome.

for 5 k 15er its 1 minute, for a 5k 18er its more than 2 minutes

for me 18.30min is 39.01 min and I ran a lot of those 10k.

if it was your first 10 k 39.13min than congratulations you will improve, means your 5k time could be impressive (could be)

and post your 5k time after the race
