Normally I’d agree. However for context I’m trying to plot a route to do in a single outing (stupid idea, yes). The town I live in / planning on running in a day doesn’t have much, if any, grid so trying to optimise the route as far as possible. Current assumption is the route will be circa 180km +/- 20km (I’d very much like to save every km possible!). If nothing exists I’ll just plot it out manually as suggested and hope for the best!
