There are training camps at Milfontes Canoe Village in the run up to Easter. The Rio Mira is a tidal estuary that winds its way through the hills to Odemira. It is perfect training for anyone doing Devizes Westminster. Especially those that need more estuary experience.
The cost is 55 euros a day full board including boat hire from either Plastex or Nelo. You can be met from either Lisbon or Faro airport.
This is the place that Longridge Canoe Club have been to every year for the last eight years. Many national teams train here through the winter. If you come alone you should be able to find someone to paddle with.
Several training courses a year here are run by one of Germany's most successful Olympian, Birgit Fischer and she says that as an athlete it was her favourite winter training camp.
If others in your group don't paddle there are many other activities from yoga, horesriding on beaches or walking the beautiful Rota Vicentina coastal path.
