In Cambridge, and needing to do a longer run (I could have done two circuits of the TAG route but that's dull) I ran out to Grantchester, Trumpington and on to Shelford, then across to the start of the Roman Road; then I came back via Wort's Causeway, past Addenbrooke's, Long Road, Trumpington Road, Trumpington Street, and back over Coe Fen, past the Sidgwick site and Grange Road.
