The bus works out well & goes Cowley Drive/Bexhill Road. Apparently they run every 10-15 minutes & the journey is just over 5 minutes from the Amex to the Cowley Drive shops.
May try the walk at some point but would think it'd take over an hour from Cowley Drive shops. Travel vouchers make the bus very affordable.
The City Council has spent millions on dopey cycle lanes in the city - if they now spent a fraction of that on a cycle track from Woodingdean to the stadium they really would be doing something for sustainability.
