COMPETITION TIME. To get us in the mood for Spring we are giving away one ladies purple running tshirt and one blue mens running tshirt (two winners). To enter just retweet and follow. Drawn at random and contacted March 19th. #runners #run #irun #ukrunchat

Sometimes promoters tweet more than once.
Tweets will only get updated when you re-fetch them. This helps you because competitions will no longer "jump" between pages when competitions get added or competitions finish while you are browsing them. Competitions get "fetched" when you login or manually re-fetch them with "Forget Ended Competitions & Fetch New Ones". Additionally hidden tweets will stay visible until you "fetch" to save reloading the page and save you from losing your position.
