Event info found from website: "
The Principality Building Society Cardiff Half Marathon will start on Castle Street from 10:00am on Sunday 1 October, with the elite wheelchair race beginning at 09:50am. The race has a staggered start to ensure all runners cross the start line as safely. The white, green and red start is at 10:00 (pens open at
09:15) and the blue, purple and yellow start is at 10:10 (pens open at 09:40). The solid background colour of your race bib (either white, green, red, blue, purple or yellow) dictates your starting pen and race start time. Please assemble at the back of your colourcoded pen, indicated via the coloured flags. You must assemble in the correct start pen for safety reasons and cannot move forwards
a pen, only backwards. The white pen is further sub-divided into elite and sub 1:30 areas on the morning of the race according to your race number and predicted time.
For safety reasons, runners must assemble in the correct colour start pen and cannot move forward a pen, only backwards."
