Besides, for the CAA, it all has to be done in one day (unless you can prove wx/tech probs caused an overnight stay somewhere). I've just done 2 CPL QCX's in the UK in the last week.
First: Barton - White Waltham - Blackpool - Barton. 320 nm.
Second: Blackpool - Shobdon - Perranporth - Blackpool. Around 500 nm.
It is a bit of a struggle to get back for last landings this time of the year. I'd have loved to have done Lands End to John 'o Groats but you have to make do with the resources, weather and opportunites available at the time.
I completely agree with KG about not aiming for minimum requirements all the time though. Make it as challenging as you can, eg no radio nav aids or GPS. Hold altitude, heading and airspeed. Adjust accordingly and get those ETAs bang on.
