In my researches this weekend, I note that the 1913 TT was won by T.Wood on a Scott------------------

The race was on the early Mountain Cicuit which was slightly shorter than the one used today--

However the race was over seven laps, a total of 262.5 miles......

It took Mr Wood FIVE HOURS, TWENTY SIX MINUTES AND EIGHTEEN SECONDS to complete the race at an average speed of 48.28 mph---

I bet he couldn't sit down for WEEKS after that---
His fastest lap was 43 mins 10 secs Speed 52.12 mph--

NOW that must have been some race-----
