I did the 81 mile route in 4:35, which is gold standard for a middle-aged 42-year old like me. Well happy with that!
Starting in groups of 50-60 meant that there were plenty of pelotons to draft, which helped.
Could have done without the rolling hills around Greenham Common though - my legs were starting to feel every little lump by that stage.
Fantastically well-organised event - cadet-marshalled parking, quick & easy sign-on, excellent timing system, superb signage, friendly & well-stocked feed stations and a great route culminating in a finish with commentary over the tannoy, and even massage, showers & changing rooms afterwards. This really sets the bar for other sportive organisers. If you only do one sportive, this is the one.
Cheers,
Darren
