Romsley has three great climbs up to it - from Grange Hill Roundabout, up Farley Lane, and for those that are tired of life, Windwood Heath Road.
St Kenelm's pass also has three good climbs - St Kenelm's Pass itself from Holy Cross, Hagley Wood Road and Uffmore Lane. Has the advantage of Nimmings NT Car Park at the top - good views and good food.
Weatheroak Hill is a good alternative to Icknield Street.
Lickey Hills - either way is good. From Catshill end it is a long slog, from Rednal its one fierce hill that gets steeper the further you go, with no respite at all until the top. And down is great both ways - either serious high speed, head down, long distance down to Catshill, or keep primary and take the big bends down to Rednal. You should be doing 40 which is the speed limit here, so be bold and only let cars past if they are desparate.
