Déjà vu in Newportpublished at 11:15 Greenwich Mean Time 18 March 2018
The organisers of the inaugural Newport Half Marathon must be wondering what they've done to deserve such bad weather.
After cancelling the event two weeks ago, the rearranged race set to take place this morning has also been postponed.
The organisers said on Facebook: "The safety of EVERYONE concerned is paramount and with the current forecast of snow, ice and a wind chill of -10 we simply cannot go ahead.
"Obviously we have a lot to do today so we will update everyone again within the next few days. Really sorry."
