For a first 10k, 50 mins would be a good time - you have to learn so much in your first few races, such as pacing yourself and not letting adreneline take over, how to dodge past slower peolpe etc. and that slows you down.

I think 45 mins would be a good time to aim for to start with - 27 mins for your 6km runs.

If you want to you can check what some 10k results are, perhaps look at ukresults web site, scroll down the race results and look at the 10k's and see where most people come in. Often the winner will be about 21 or 32 mins, 37 mins is good going -quite tough, and 45 mins where most people are.

If you are trying to get faster times then you stop running for so much fun and more to race.
