Having hit the ground twice at speeds in excess of 60MPH I can vouch that it hurts. The first time required hospitalization and I still have to wear my hair longer in the back to cover the scars, the second time it took a couple of years for the color to come back on my hands, the road rash was so bad.
Each time was on a motorcycle and it went from perfectly fine one second to sliding down the asphalt hoping the helmet would hold up the next. Jeans ripped about off, a leather jacket ruined and immense damage to the bike. (a Matchless 750 and a Harley XLCH)
The most recent of those was in 1967 and were lessons well learned. At my age I appreciate the fact I can go 30 or 32 MAX but simply don't cruise above 20, hoping I can survive that speed. With shorts I tend to slow it down a little more if conditions warrant. A few years ago, on this same bike, a crack in the sidewalk wobbled me into a 3' high concrete barrier on a bridge. The skin was effectively removed from my right leg in a six inch path from my ankle to my knee. It wept for weeks and PO'd my wife as it tended to ruin bed sheets. That was at three or four miles an hour. Oh, even at that speed it threw me over the barrier onto the road. Fortunately no cars were coming and my head never hit the ground which saved my helmet from getting scratched.
Go for it, realize that lacking full suspension and tires and wheels rated for that speed though can be hazardous to your health.
