A couple of lads in my club recently got under the hour for 25 miles. Quite rightly they were well pleased. It got me thinking. It seems now that a 45 min ride is as rare as a 49 minute ride was when Alf Engers first broke 30 mph over 35 years ago. When I started racing in the early 60s aero meant riding on the drops. Training consisted of getting the mies in usually on 66 fixed and early season reliability rides. With the new aero TT bikes, wheels, clothing, helmets, power meters, coaches, training regimes, is a 55 minute ride now the equivalent to getting under was 20 or 30 years ago?.
