Five of Guernsey's leading athletes will not take part in this summer's Island Games in Bermuda.Olympic marathon runner Lee Merrien, former Great Britain hurdler Dale Garland, island 400m record-holder Tom Druce and Island Games 100m record-holder Kylie Robilliard will not run.Louise Perrio, who won 10,000m gold two years ago, is also not taking part.Perrio, Robilliard and Druce are all focusing on the British Championships which coincide with the Island Games.Garland, who holds the Island Games 400m and 110m hurdles records, is unavailable after becoming a father, while 2011 half-marathon gold-medallist Merrien, who has a hip injury, is unlikely to travel due to his programme as he bids for a place at this year's World Championships.Seven of the 17-strong squad will make their Island Games debuts, and despite not having their leading athletes, Guernsey team manager Steve Allaway told BBC South West Sport the Games provided a chance for some of the island's future talent to get experience of a major meet."We're still expecting some good results, although we probably won't be top of the medal table this year," said Steve Allaway."But we're not looking at the medals as much, but the potential within that squad.“By the next Games in Jersey these athletes will be solid senior athletes”Among the youngsters who will be making their debuts are 15-year-old Katie Rowe, who is ranked seventh for the Under-17 age group in Great Britain at 1500mAllaway said there were also high hopes for 400m runner Sam Wallbridge and throwers Zoe Fitch and Ali Higgins."They're throwing excellently and lady throwers have always been a weakness with the Guernsey squad. On the day I believe Zoe could even medal," he said.Jon Beard, chairman of the local organising committee, commented : “Guernsey’s situation is much the same as ours is in most years in that injury or other meet commitments have prevented the very top athletes from competing.“That being said we have always done well with those who have competed.“The Guernsey Athletics website (http://www.guernseyathletics.org.gg/results/2013/fixture.aspx) shows what a strong and varied season they have and so I know that we will still get strong competition from them whomever they send.”The Island Games take place from July 13-19.Guernsey athletics squad for Bermuda 2013: Josh Allaway, Glenn Etherington, Hywel Robinson, James Sermon, Sam Wallbridge, Michael Batiste, Natalie Whitty, Simon Murphy, Ben Wilen, Mike Wilesmith, Steve Dawes, Emma Le Conte, Sarah Mercier, Tom Swain, Katie Rowe, Ali Higgins, Zoe Fitch.
