Revised for late 2019:
You can “follow me” on an organised event in two ways:
If I know in advance you want to follow me (and I set it up correctly) you should receive an email from me/Wahoo when I actually start with a link – click on the link and you’ll see where I am and also the route I should be following.
Go to Events Calendar at the bottom of this page, click on the current event and you’ll see a map of my route with markers showing where I am – the markers should appear every 5 minutes or so (a mile and a bit). If you visit some time after the event has actually started, you might not see the event – in this case just click on “View All Events” and look for the date.
