Erm, how long are your other run(s) if you're doing 20 miles per week but a long run of 12-16? That doesn't leave very many miles for other running. Maybe you need to start building more running into the rest of the week to give you some sort of base to do the long runs from.
If Marx were alive today he would be writing that 'celebrity' not 'religion' is 'the opium of the people'. Who cares about these non-entities? It is a complete waste of BBC tax payers money.

Let the luvvies look elsewhere for work.
