Adventure Hub Welsh Ultra This 100 k coastal ultra on the Anglesey coast path started close to Holyhead taking an out and back route to ???? . The race started at 8 am and by that time the sun was already cracking the flags there were 32 starters for the Ultra and around 10 for the Marathon . These coastal races are tough as there is little or no shade on these hot sunny days . The terrain is rarely flat with lots of steps and steep slopes to contend with.
