Yes, the Manx government has seen fit to cancel the traditional Senior race day Bank Holiday!!
I know that there won't be a Senior race this year, but there wasn't in 2001 & they still had the Bank Holiday
 (I believe, but I cant actually remember, to be truthful!)
Anyway, if you think there should be a Bank Holiday there's a petition here you can sign here -
