Notes

• BLUE markers are previous runs. The RED marker is the next run.
• GREEN markers are subsequent runs. 
• YELLOW markers are "Special" Runs
• If you click on a marker you will get some information.
• You can drag the map around. Use the control on the left to move and  zoom.
• HINT not all of the markers are on the map at the start! (Isn't Berkshire a big county?)
