Peter Horne made his international debut off the bench against Samoa in the opening match of the quadrangular tournament in South Africa in June 2013 and then suffered a serious knee injury in the next match against South Africa. One year on and, recovered from that injury, he enjoyed his first start for Scotland in the 19-17 win against Canada in Toronto.
He was rewarded with his first home appearance, at BT Murrayfield, in Scotland's 2015 RBS 6 Nations fixture against Italy and then impressed in the Summer Test match against Ireland in Dublin, threading through a gap from outside the 22 to run in his first international try.
He made his debut for Glasgow Warriors as a replacement in the Magners League match against Ulster in March 2009. In September 2011 he scored the winning try in Glasgow’s RaboDirect PRO12 victory away to reigning European champions Leinster It was the first time the Irish province had lost at home in almost two calendar years (29 matches). He is a product of the prodigious Bell Baxter High School/Howe of Fife rugby combine and has gone on to represent Scotland at under-19, under-20 and 7s levels. He was awarded a full-time Scotland 7s contract last season in the lead up to the 2011/12 HSBC Sevens World Series after captaining the Glasgow Warriors to victory in the Glasgow City Sevens. Injury restricted his involvement in the abbreviated game but he has made seven tournament appearances for Scotland and has topped a century of points through 17 tries and nine conversions.
Earlier, he scored all of Scotland’s points with six penalties in the 18-17 win against Wales in the 2009 Six Nations Under-20 Championship match at McDiarmid Park, Perth. His tally was a Scottish record in the championship, and he added a penalty in each of the subsequent matches against France and Italy. However, that tally of 24 points was passed by Robbie McGowan later in the championship with 27.
Peter took his under-20 year’s tally to 63 points when he scored 39 in starting in all five matches in the IRB Junior World Championship in Japan in June.
Two years earlier Pete was in a group of Fife youngsters who achieved a rare double, playing in the Bell Baxter High School team who won the Bell Lawrie Scottish Schools Cup and then in the Howe of Fife squad who lifted the Scottish Youth League Cup. In season 2006-2007, too, he was in the Bell Baxter team who won the Royal Navy schools sevens.
In 2008 he played international rugby at both under-19 and under-20 levels. He was in the Scotland team who beat Italy in the under-19 international in February at Parabagio, near Milan, and he then played for the national under-20 squad in all five matches in the IRB Junior World Championship in Wales in June, starting in three of the games. He moved from Howe of Fife to West of Scotland for season 2008/09 and has also played club rugby for Dundee HSFP and Melrose.
Outwith rugby Pete won the East and West of Scotland under-16 tennis doubles championships with Jonny McNab. Pete’s father, Garry, coaches the Howe of Fife first XV and his younger brother, George, has played age-grade rugby for Scotland.
