Submitting two timings. 3h 17m 06s for the coast to coast, and 7h 04m 54s for the double (coast to coast to coast). Slight deviations from the official route were made (km 0 to km 1.1, km 5.1 to km 5.7) due to renovation works on the official route, but otherwise stayed entirely true to the route. Run was supported, with pacers for the first 10k and last 20k.
