Ive been for a ride round Alton water (in suffolk) today, its just over 8miles round it and the surfaces vary from mud to stone to concrete in places with loads of small but knackering hills, (which i didnt know about as it was my first time round)
Anyway i pushed myself all the way round without stopping and even had to use the granny gear on a few hills, what i thought was going to take me just over half hour took 50mins,
I worked out that my average speed was 9.7mph (correct me if im wrong) is this about average? only asking as i was a bit disappointed that it took so long even though i was pushing so hard.
It's a case of how long is a piece of string I'm afraid....
.... the amount of climbing, how exposed your are to the wind and whether you're riding with or against and the amount of mud can have a massive impact on speeds .....I can ride same trails in winter and summer and the average speed will be max 10 km/ph in winter and min 16+ km/ph in the summer.....
...also, for a short blast the average speed will, obviously, be higher than on an all day epic....
...even tyre choice can make a difference - with soft rubber tyres noticeably dragger and slower on hard pack surfaces....
....best bet is to keep a mental note of your average speeds on the trails you ride regularly during the year and you'll soon get an idea of your typical; speeds but will also start tom note how much quicker you can start to ride if you keep at it regularly.
All that said - when planning longer (half to full day) rides I've found an average of 10 kmph works fairly well to provide a sensible estimate for how long the ride is going to take - but I'll adjust this depending on the terrain I'm riding - e.g. for big rides in the Lakes I'll add 30 min extra for each hour I think I'm going to be out
