Today’s run is about 30 miles taking a large loop out to Chiswick, where my friend Suzanne from our ACME studios is showing. After looking at her works, which are studies of Brixton market, I head north to Acton and then east along the Grand Union Canal. As there are no galleries here I visit some places I have worked in, though of no relevance to Gallery Runner.

Eventually I arrive at Hyde Park and see the beautiful new pavilion by Diebedo Francis Kere. It looks like a chieftain’s palace with slatted roof and stained block-wood sides whilst being structured around an immaculate white metal frame that gives it further credentials as a piece of cutting edge architecture. Then I head on to the Royal Academy. After having photographed a couple of great works by Danny Rolph and Frank Stella, that I remember from my previous visit last week, I note the number of my painting and check the front sales desk to see if it has a red dot next to it yet. No, is the answer to that one.

Round the back of the RA on Old Burlington Street is Stephen Friedman Gallery. It has been influential in this year’s RA Summer Exhibition because of the contributions from its own artist, Yinka Shonibare, both by his curating and from his artworks there. In Stephen Friedman Gallery itself there is an unlikely but fascinating exhibition of material-based artworks that explore stretched canvas through a multitude of distortions and interventions that have been enacted upon it by sixteen artists.

Finally today I check out the RA School’s degree show. Work by Josephine Baker-Heaslip catches my eye due to great patterns she has created with stacked bricks whilst containing them in their entirety within wooden cut-out structures that hold the various brick forms in place. The bricks themselves have been painted on some of their faces with earthy but bright colours and make lovely artworks. After a quick half pint and the time now seven and a half hours past my departure time this morning, a marathon already achieved, there is a last hour remaining for the return home.
