http://www.slow.routegadget.co.uk/rg2/#145&cou...Started pretty well; not the best route to 1 and 2 but okfor legs with little time to pre-plan. Happy with 3,4,5; 6 I should have planned better given the long run from 5; I was anxious not to miss the AP from the main road, but in hindsight it should have been so obvious it would be been okay to plan ahead more.
Non-wiggly route to 7 worked well although longer. Didn't like my route to 11 at the time although looking at it now it's not terrible.
First mistake was really 15 - 14 didn't beep, but dibber flashed, went back to repunch anyway and same thing happened - that's happened before and it's been recorded, so I didn't waste time punching the map, but it knocked my concentration and I set off back towards 12. Noticed before too long though, and not a terrible route, more time through faffing than route. 30s maybe.
Only other error was a biggie unfortunately; and in the same vein. Feeling pretty smug about getting 20-21 right in advance, navigated perfectly to 27 and then from there to 26, then no wait, 25 should be before 26, so got 25 first, then to 26...no, wait, ..., damn.
+3 mins and 11 places :(
Rest was ok, except I think my route from 27-26 was better than my eventual route from 26-27 (unfortunately I'd forgotten about the carefully planned original).
Some good legs although the course felt unnecessarily long; the extra loop up to the Gherkin felt superfluous.
