For a run event that doesn't take itself too seriously then check out the Tower of London Run. It attracts runners of all abilities and the 1k looped track will give you the decision of exactly how far you want to run, jog or walk.
The course itself was freshly laid grass. It was really spongey in places and was quite pleasant to run on. One section of the course had really strong headwind so I tucked behind others for that bit.
Five minutes off last years Sports Relief event.
