Following on from my last post about my bookmarklet to view any Strava route, activity or segment in 3D, here is the follow-up post about a far more simple bookmarklet that will swap out the default Google Maps found in the Strava website for a choice of Open Cycle, Landscape and Street Maps or the Ordnance Survey maps in the UK. At least here in the UK the Google Maps can be rather limiting from a cycling or running perspective due to a distinct lack of detail, particularly around off-road routes. Fortunately the Open Maps (and even more so the Ordnance Survey maps) have detail in spades and with a bit of JavaScript magic we can swap out the Google Maps for the alternative map of our choosing.
