Only rides I have ever gone out to go fast on were training rides for big rides I was doing.
I knew that when we could do the 30 miles in 150 minutes and do the 2,400 ft of climbing without falling off more than twice- Then we could do the 100 miles in 1 day and survive.
OK not solo but one single bike. The Offroad Tandem.
