My commute is 12k and takes me about 40 minutes. The first bit is down Leytonstone High Road, which is fine in the morning as it’s pretty quiet, then across the Olympic park and through Victoria Park, which again is fine if it’s daylight and Victoria Park is open, otherwise it’s a horrible ride along the ‘Quietway’ of Old Ford Road.
Then it’s Bishop’s Way with parked cars on one side and cars diving to overtake you between traffic islands on the other. Then it’s Hackney Road, with buses, cars and other cyclists. This bit is actually okay as the traffic speed is pretty slow. I stay right out in the middle of the lane and overtake on the right at all times. I then cut up to Pitfield St, down through the crossing and take my chances among the shared space cycle lanes and footpaths, construction traffic, scaffolding and buses running parallel to Clerkenwell Road rather than trying to cross Old Street roundabout.
My preferred route from there would be to head west on Clerkenwell Road all the way up to Gray’s Inn Road, but the road works and bus diversions mean that it’s horrible at the moment, so I now go a bit further to get onto the segregated lanes on Skinner Street.
