On my "two tunnels" run

After a few days off, I felt confident enough to venture out for what was scheduled as a two-hour long run - enough time to go down to Woolwich, through the foot tunnel there and then run via the Royal Docks, Blackwall (blip the O2 from the north side for a change) and Isle of Dogs, and down to the Greenwich foot tunnel to complete the loop (19km in total). I had to delay my start until the rain stopped but it didn't rain anymore - a bit grey overhead all day, though.
