Bike Pacing Chart by Common Distances
Below is the cycling pace chart that converts your MPHs into time for various distances from 10 miles to 112 miles (Ironman Distance). For example, if you’re cycling at 20 MPH for a Half Ironman (56 miles), it would take you 2 hours and 48 minutes.

I ride 12 miles in around an hour at around 245-250 lbs i try to do the first 5 miles in around 15 minutes i been hitting right on 15 minutes the past couple of days, then i want to work on getting the total workout time down, i was wondering if them are good times and if i could get any tips (especially with whats foods for that type of training)
Most bikers always have a goal to hit when on the road. An eight-mile distance is an average goal for regular cyclists. So, How Long Does It Take to Bike 8 Miles? If you are a newbie and want to explore the cycling road, it will take you more than 48 minutes to be able to complete the distance. A beginner cyclist will have an average speed of 10-12 mph. A regular biker can finish the distance in 48 minutes or less. The last is some professional bikers only take 2.14 minutes to cover a mile. It will only take them less than 20 minutes to finish an 8-mile ride.
In the cycling speed calculator, the speed in MPH is correct but the value should be X1.609 (instead of ./.) to yield the KPH.
This is a really great resource but hardly just for “newbies.” I use it to calculate my goal pace for a 70.3, but it works for Olympics, Sprint and Full distance after all.
