Route information
This is one of the flattest courses in the country. SportiveUK went out of their way to find a route where competitors wouldn't have to climb a hill. This is an incredibly popular event and due to the lack of elevation gain, tickets do go very fast.
Distance: 100 miles
The course starts in Thorne and heads south towards Hatfield. From there, riders will head north through Rawcliffe and onto Airmyn. Competitors will then hug the Humber River to Adlingfleet, before heading south through Suswoth, Beckingham and onto South Leverton. From here riders will complete the loop by heading through Retford and Bawtry, before arriving back in Thorne. Feed Station: Keadby – Clayworth
Distance: 65.7 miles
The route is identical to the 100 mile route up until East Ferry. At East Ferry riders will head West into Epworth and will complete the loop by passing through Belton and Sandtoft, before arriving back in Thorne. Feed Station: Keadby
Distance: 25.1 miles
The short distance follows the 100 mile route closely until Rawcliffe. At Rawcliffe, riders will head South through Moorends and then will finish in Thorne. Feed Station: Food on return to HQ

Sportive HQ's logo
Sportive HQ
Sportive HQ was formed by Matthew Porter in 2014, after having approximately 10 years experience in the organisation of various types of cycling events. It was very much the feeling that sportives were becoming more expensive over the last few years and that need not be the case, value for money can be put alongside quality events. Sportive HQ works alongside local clubs to produce events that riders will want to do every year. We listen to what riders want from an event and endeavour to meet those requests. At Sportive HQ we like to keep things simple, ample free parking, showers, changing rooms, a timed event with well spaced, well stocked feed stations and routes to challenge everyone of all abilities. Sportive HQ helps in the production of many local charity events and have helped raise, alongside local clubs, in excess of £50,000 for local charities over the last few years.

Did the 100 Mile in 2019
This was my very first event with sportive HQ and I have to Honeslty say I absolutely loved and enjoyed it. The event was well organised with guidance and directions, plenty of informations given well ahead of time with an excellent price value for the event. I returned for flat 100 south and rode flat 200 with them. Will definitely recommend.

My mate and I did this ride for the first time in 2018. We have done a few Sportives. This one is by far the best organised. Matt and his team are very professional. The feed stations, medical provision, signage are second to none.

Excellent Event. Hubby and his friend rode it and I volunteered to help. I have volunteered at other cycling events. This is by far the best organised I've been to. Matt and his team are amazing. Everything is thought of. Nothing is too much trouble.

I've done 4 or 5 Sportive HQ events in the last 2 years. They're always well organised with great support from the organisers and a fun atmosphere. I'd recommend their events to anyone but particularly those who want to do their first sportive, as I was, due to the high level of organisation and making it an accessible event for beginners.

Great course for a PB. The staff were friendly and helpful and made the event easy to find, park and get ready for. The only down side was a long wait to get started as the event is so popular there were hundreds queuing to get going. However once on the course it was great. For a big distance and trying to keep it flat the course was well planned. All in all a great day out.

A great day, a great route, and definitely a chance to get a personal best. Will be back again next year.
