They didn't have GPS back then, so they just rounded up. Yeah I know, you measured the route with your car odometer sometimes, but admit it, back then, everyone rounded up a little bit. 100mpw in 1970 is the equivalent of about 83mpw in 2026.
Also, a lot of times they may have been doing "reverse badger miles", that is, using time watch time to measure distance, and assuming they were going about 7:00 mile pace the whole way.
Are you one of those era or are you imagining how life must have been pre Garmin? Usually you odo would have been out by max 2% depending on tyres etc, but there used to be km (or miles) check distances, usually 5km, you still find a few but not so common, to 'check speedo'. Then you also had races and time trials measured by wheels which gave runners asense of pace. That is something you dont find in modern runners, no sense of pace, they need garmin to tell them.
You are really saying that someone would run 8.3miles at say 6mim and write it down as 10miles at 5min!!
Back in early 80's I ran an '18.4km' tough mountain race in 62:20 and placed 3rd. I've always thought it may have been short because it equilibrates to 71:20 HM, and I was probably in 70min flat course shape
I measured it with Garmin in 2010, and guess what? 18.4km...that was probably my best year of running, most of PB's from that time
