To date, I have been around the Newcastle parkrun course 80 times (officially) and completed many "freedom runs". I also use the course for tempo and marathon paced runs so, to cut a long story short, I know every inch of our parkrun.
However, we have run a number of variants of the course since Newcastle parkrun started in January 2010. Recently, we went through a period of running the course in reverse but have returned to the original "clockwise route" due to some safety concerns. We also have an alternative route for two weeks in June when part of the course in occupied by "The Hoppings" travelling fair. The run takes place on The Town Moor. The Town Moor is a large area of common land in Newcastle upon Tyne. It covers an area of around 400ha, and is larger than Hyde Park and Hampstead Heath combined, stretching from the city centre and Spital Tongues in the south out to Cowgate/Kenton Bar to the west, Gosforth to the north and Jesmond to the east.
Anyway, down to the description of the course itself (the distances given are cumulative course distances). The start is on a tarmac path and this takes you 0.2 miles to the main path that runs from South to North across the whole town moor. This path is fairly straight and undulating and takes runners to 0.92 miles to the first gate on the course. Manned by Newcastle parkrun legend Malcolm Craighead (one of our most decorated volunteers) "Gate 1" has recently been renewed after the original gate mysteriously disappeared. Runners then turn right onto Grandstand Road. This fast section is downhill and usually has the prevailing westerly wind behind you. Grandstand Road can be seen below (looking up the hill the opposite way to the runners).
On the whole, the Newcastle parkrun is course is fast but PB attempts are usually limited to rare wind-free weekends.
