I've increased my distance to 8 miles, later in the week or next week I will do 10.
Today I did my 8.1 miles in under an hour, say, 50 mins. The rode is on pretty bad old roads and some OK roads. It involves a good few kilometres of climbs also. It's by no means flat or main road riding.
Does this sound like an OK time for a beginner? What should I be aiming for?
