This chart allows sufficient time so that the ride ENDS 15 minutes before sunset. Ride times use the average minimum speed for the ride rating (A 18 mph, A/B 16 mph, B 14 mph, B/C 12 mph C 10 mph) AND 15 minutes for each rest stop. The ride rating chart in the front of each newsletter has all the info on the number of rest stops and average speeds. Estimate rest stops as 15 minutes.
The reason for this scheduling policy is that stopping for a repair or a route mistake for long, late rides frequently meant returning after the sun had set. The time cushion helps prevent the sundown panic which causes people to roll through stop signs and do other risky things to avoid getting caught in the dark.
