Living in a metric country I don't particularly aim for an imperial century - but then I don't aim for any particular distance either. I do 8 - 10 metric centuries a month.
My two most recent century training rides were 139km (86mi) and 1100m (3608ft) climbing in 4h 28min and 31km/h (19.2mph) and 132km (82mi) and 1349m (4425ft) climbing in 4h 25min and 30km/h ave (18.6mph)
The longest so far this year solo was 144km (89mi) and 1503m (4931ft) climbing in 4h 49min and 29.8km/h ave. (18.5mph)
In terms of long days, well I did do a charity Pro-Am race in my 20's that covered 1000km in 4 days. Went through a mountainous region, fairly lumpy as I recall. No idea what the average speed was. I don't think I've done more than 100km off-road on my MTB in one ride either. Guess I need to get some long rides in!
