Preview - Dublin City Triathlon Round four of the 2017 Super Series kicks off Dublin City Triathlon at 8am on Sunday morning.With its city centre location and technical bike course, DCT has long been one of the highlights of the triathlon calendar and this year looks to be no exception.More than 1,000 athletes will line out on Sunday from beginners and relay athletes right up to some of the country's best draft legal racers and national champions.There’s a wealth of information on the course, wave allocations and pre race advice on http://www.dublincitytriathlon.com/ and on DCT’s social media accounts.Super Series PreviewDCT’s Super Series race is held over sprint distance and like the other races in the series, is draft legal, meaning athletes will get the chance to work with one another against those in front and behind them on the 20km bike course.The swim takes place in the River Liffey which has traditionally benefitted slower (relatively speaking) swimmers as the lack of space gives them the chance to swim on the feet of the stronger athletes.The bike course is technical but quite fast, with smooth roads, a number of long straights and some quick descents before the 5km run which features a hill in the first half and takes place almost entirely on tarmac.Last year’s DCT. Last year Chris Mintern beat a duo of overseas athletes to win the men’s race while Susanna Murphy won her first (and only?) domestic race of the 2016 season. http://www.triathlonireland.com/News/2016/Mintern-and-Murphy-Win-Dublin-City-Triathlon-Super-Series.htmlNeither are on the start list of the 2017 edition and so two new winners will take the titles at one of the season’s most high profile events.Men’s RaceThe men are first to race on Sunday, entering the water at 8am.Last year’s winner Chris Mintern isn’t the only high profile absence as demands of the international racing calendar mean a number of this high performance development colleagues, including Con Doherty, Kieran Jackson, Darren Dunne will also sit this one out. And following his top 20 performance at IRONMAN Dublin 70.3 last weekend, Aichlinn O’Reilly also sits DCT out.The result is a wide open field - who will win is hard to predict but the main contenders are as follows:Alastair RogersGB athlete Rogers has had a series of podium finishes in his many trips across the Irish channel and will surely be eyeing DCT up as his chance to finally move to the top step. Rogers was 2nd at City of Derry in May and 2nd at last year’s DCT.Cillian TierneyAfter getting his leaving cert out of the way, Cillian Tierney had a late start to the triathlon season but certainly hit the ground running with 2nd place at Two Provinces Triathlon and 7th against a very strong non drafting field at Caroline Kearney Triathlon.Richard HortonFourth place finisher at the Super Series race in DCT in 2015 and 4th place at this year’s City of Derry Super Series event, Richard Horton is no stranger to racing in Ireland. Horton is a former duathlon world champion at junior and U23 level and was the 2016 British duathlon champion. James MinternMintern was one of the standout performers from Round 3 - finishing a superb 4th in his first Super Series race. The teenager (and brother of National Champion Chris) has a string of race victories to his name this season, which are bound to give him confidence heading in to DCT.Tom McEneryTom McEnery won DCT’s non drafting olympic distance event in 2016 on his way to the overall National Series title. As a Cat 2 athlete McEnery has mixed National Series with Super Series racing in 2017 and proved himself more than capable of competing thanks to his strong swim ability. James WaltonWalton finished 6th at Two Provinces with a very strong swim and claimed some scalps at the Sprint Distance National Champs in Derry at the start of the season where he claimed 7th place.Others to watch on Sunday include the always competitive Brendan Murphy, the fast improving Ben Ryan, Sebastian Helka, 2016 National Aquathlon Champ Harry Speers and Dave Richardson.Women’s RaceA large field of 19 women are due to start DCT’s Super Series race and with last year’s winner, Susanna Murphy absent a new name will get all the limelight on Sunday.An intriguing race could be in prospect with Heather Foley going up against Ailbhe Carroll and the winner of the last round of the Super Series Elizabeth Carr. Throw in the presence of Ellen Murphy, Niamh Corry and Aoife Fay and we have a tight and unpredictable race on our hands.Heather FoleyFoley heads in to every domestic race as the favourite, such has been her dominance in recent years. Foley has won the duathlon, sprint distance and standard distance national champs this year so far and with her all round strong game is hard to overlook on Sunday.Ailbhe CarrollCarroll finished 3rd behind to Foley (2nd) at this year’s Super Series race in Lough Cutra and was the runner up to Foley at City of Derry in early June. Since then, she has concentrated mainly on international racing, where just this month she finished a very respectable 20th at ETU Malmo. As well as earning her international points, the performance is notable as Carroll finished four places ahead of Foley, making DCT a much more interesting prospect.Elizabeth CarrCarr has been the revelation of the 2017 season, coming from an athletics background to make huge strides through the course of the summer. This culminated with a stunning victory at Two Provinces in round 3 of the Super Series. The competition will he tougher on Sunday, but Carr’s full ability is yet to be known.Kirsten HuysamenHuysamen regularly finishes towards the front in the Super Series, and has scored two 4th place positions at Two Provinces and Lough Cutra.Ellen MurphyThe silver medalist at Caroline Kearney Standard Distance National Champs, Ellen Murphy has a strong all round game and is especially adept at the bike-run combination.Aoife FayAoife Fay has steadily improved her placings this season so far. Beginning with a 10th place finish at City of Derry, she finished 2nd to Carr at Two Provinces and won the silver medal at the National Aquathlon Champs a few weeks later.Erin McConnellProbably the strongest swimmer in the women’s field, McConnell has led almost every race she has entered this year so far. Her 7th place at Two Provinces shows she is beginning to put the other aspects of her performance together.LIVE COVERAGERacing begins at 8am and all the action will be covered as it happens on Triathlon Ireland’s Facebook page, instagram and on twitter.
