Running

Hey Sparky

Few sporting events id recommend in the UK over most that can be found abroad.

The RIVIERA CLASSIC is a great race.
Starting in Italy, through france and finish running along the F1 track in Monaco.
Although 23.8km on paper but it goes over cap-martin so it feels more like 30.

There is a 10km distance on offer too

Sounds amazing, but probably too pricey given Paris.
