The Flat 100, is possibly the Flatest sportive in the country. Not everyone wants to find a Top 100 Climb on an event so to buck the trend we have sought out a route where you don’t have to climb a hill. Some people do find this a big attraction and the event is very popular, so join us for a great day out. It really is a must do ride, the feedback we get tells us this and entries go very fast so be sure to enter early!

  • Did the 100 Mile in 2019

    First Sportive (and first century) and it beat all expectations (despite a heavy crash)
    The food at the feed stations tasted nice (the cakes !!) while ideal for a long ride
    the Mechanics was ace - fixed my bike and allowed me to finish under 6h
  • Did the 65 Mile in 2019

    A fantastic day as always, this is the 4th time I have done this ride. It is very well organised and everyone is so friendly helpful and encouraging . The feed stops are the best I have ever experienced ( have done other sportives which cost more and didn’t even get a sandwich ) Great value for money. Well marshalled and well sign posted. Well done Matt and team
  • Did the 65 Mile in 2019

    Great organisation, Fantastic route well signed feed stations are great great value for money and the merchandise is also great quality
  • Did the 100 Mile in 2019

    You will never find better signage. Arrows everywhere. Feed stations are excellent, and the chap who is in charge (never know his name) will go out of his way to assist. Last event I did I forgot to bring a spare inner tube. Went to registration to see if I could buy one. Within 30 secs one was given me. No charge !!.. Cannot fault hem.
  • Did the 65 Mile in 2019

    We have done this Sportive for the last 4 years, definitely my favourite, the communication beforehand is superb, everything is sent out in plenty of time, on the arriving in the morning the organisation is very slick and relaxed, the signs for the various routes were clear and Marshalls dotted about were cheerful and friendly, the food stops are excellent, will definitely be signing up for another on soon.
  • Did the 100 Mile in 2019

    Done this four years in a row, gets better n better every time!!! Excellent in every department. Would highly recommend this to everyone
  • Did the 100 Mile in 2019

    This was my 2nd flat 💯 sportive, this event is very well organised with superb feed stations. The route is so well signposted that you don’t need any downloaded maps. Do it you won’t be disappointed.

  • Did the 65 Mile in 2019

    Very well organised and run, as always with Sportive HQ. I happily recommend these events to the women riders I encourage as a Breeze Champion, as they feel very friendly and inclusive. The marshalling and medical backup are excellent.

    No need to download the route, signposting is exemplary.

  • Did the 65 Mile in 2019

  • Did the 100 Mile in 2019
