An insight into how a road race course is measured
DAVE GORDON GIVES AN INSIGHT INTO PREPARATIONS FOR SEPTEMBER’S HARROW HALF-MARATHON
JUST what are five blokes on bikes doing in the grounds of Harrow School at 4am on the first Sunday of July? As night turns to day, it looks very furtive and suspicious. Fortunately there’s an innocent explanation. With exactly 11 weeks and five hours to go, it’s time to get the Harrow Half Marathon course officially measured and certified.
One of the five is a real expert with a global reputation – Hugh Jones. Not only was he a talented runner, winning the London Marathon in 1982, but he’s also measured the London Marathon course and indeed every Olympic course since Atlanta in 1996.
Jones uses a counter on the front wheel of his bike, which he’s calibrated against distance and converts those numbers to arrive at an accurate measurement.
As we set off, he is escorted by James Shipley from ActiveTrainingWorld, who is helping to stage the event, plus Kevin Concannon and myself from Harrow AC.
Ian Slaney, Harrow Council’s traffic supremo (who has plotted the route, the road closures and bus diversions) will drive behind, to protect Jones from any traffic. The race will start in the grounds of Harrow School, gently rising close to the top of Harrow on the Hill before dropping down to Harrow town centre.
Jones describes the first mile as “very challenging” but the course soon settles down as we strike out. It’s getting lighter but unfortunately with the daylight comes light drizzle. In general, Jones says the problems with measuring tend to be struggling against traffic but “this was surprisingly easy compared to what I thought it might be but that’s largely because we started at 4:10am and finished by 6am on a Sunday morning. It’s the best time to do it particularly in the summer, when it’s light for most of that time.”
Jones’ approach is meticulous, as you would expect. Stops are frequent as he makes notes on one-mile markers and gets clarification on which roads and lanes will be closed to traffic. They all affect the racing line.
At one stage Jones confirms with Slaney which railings on the edge of Headstone Manor will be removed for the race. The course distance has to reflect all the corners, which the runners could cut on race day. It’s obviously crucial that the race distance is accurate and fortunately it’s very rare that mistakes are made.
The Harrow Half on September 17 is a course of contrasts as the route goes past iconic venues and shopping centres, and through parks and open spaces. It’s a good route for spectators too with plenty of good and accessible vantage points.
Jones remembers running the original Harrow Marathon and Half Marathon in the 1990s and also measuring the course back then.
He says he wouldn’t describe this course as the most exotic he’s measured; that honour goes to the Tibet Sky
Marathon, run within sight of Mount
Everest. Nevertheless, he’s positive about the Harrow Half course.
Despite the challenging start and the last 400 metres he describes jokingly as “suicidal” – it’s a steep downhill section onto the Harrow School playing fields – he says “other than that, it’s beautiful”.
