Recently 1,500 cyclists chose one of the toughest, hilliest sportives in Britain: the Wiggle Tour of the Peak, based in Britain's most popular national park. Now event organisers, KilotoGo shift to the other extreme by heading to the flatter terrains of Essex - with its rolling, sheltered lanes - and the straight, quiet and fast roads of the pancake-flat Fens. 

First up is the Wiggle Essex Explorer, taking place on Sunday 8 June 2014 and offering routes of 100, 60 and 39 miles. Every mile of each of the 3 route options is in the large county of Essex. Often thought of as almost an outreach of London, if you don't know Essex then you are in for some wonderful cycling surprises. The routes take advantage of the lovely countryside, although riders will steal the occasional glance of Canary Wharf, The Shard and the City of London from time to time. 

Around half of the mileage on each of the three route options uses the same roads as the third stage of this year's Tour de France - held just 4 weeks later. Quiet, well-surfaced lanes and pretty villages will be the order of the day. There's a great new event HQ at Ongar leisure centre for 2014 too, and all routes leave to the north, immediately swinging west onto Tour de France roads. 

Two weeks later, on Sunday 22 June it will be the turn of Peterborough to play host to KilotoGo, when the Wiggle Flatout in the Fens rolls into town. The event offers 3 route options, including an epic 152 mile route (the UK's original 150+ mile sportive) and a 112 mile distance that's ideal for those training towards an IronMan. This is a sportive that challenges riders in a completely different way. 

The Fenlands present many challenges for those taking part, but hills definitely aren't one of them. The event, which attracts over 800 riders, is based in some of the UK's flattest countryside across the counties of Cambridgeshire, Lincolnshire and Norfolk. 

There's not a signal significant climb anywhere on the route, but plenty of superlatives. Riders will pass the lowest point of altitude in the land, at 4 meters below sea level, courtesy of some very impressive Dutch dyke-style engineering. Based from Peterborough, the event takes places on the weekend of the Summer Solstice to give riders the maximum amount of daylight hours to complete their chosen route. 

Both events offer KilotoGo's 'Ticket to Ride' service for those participants who sign up in advance, meaning no registration queue on the day, just turn up and ride having received everything you need in the post in advance. 

All finishers, no matter when the sign up, will receive a HIGH5 taster pack, a pro-quality 750ml water bottle, a goodie bag, a finisher's medal, a certificate and a short video of the moment they cross the finish line. 

Both events will also feature electronic timing, event photography, industry leading signage, well stocked feed stations and mechanical support. Furthermore, motorcycle outriders and paramedic backup will be on hand should it be needed.
