You might have got nearer to that if you didn't collect one extra!
I did too! Another senior moment. Up the hill between 17 and 7 I counted both the punches and the map three times and convinced myself I still needed 7 controls so diverted to 30. Would have been 4th; I passed the 4th placegetter coming in the opposite direction about 80m before no. 30, by the time I punched it and ran back round the corner I could just see her 150m ahead. She ran the same final route as me but I couldn't make any impression. Then 2 guys came past across the oval before the finish.
If it's a senior moment for you, what do I call it for me when I just completely ran past a control that I had intended getting?
