Long Manly route

My old Manly route via Burnt Bridge Creek, Queenscliff, Shelley, North Head, Collins Beach and Manly to Spit cutting back from Tania Park. Felt really sluggish for the first 10k (43:20), took a gel after an hour then it was a different story. Felt magic in the second half finishing strongly in a course PB of 1:58:58. There could be something in this. I always run crap first thing in the morning so maybe it's partly nutrition. I think I may take a gel pre-C2S next week.
