Also note to self - better get some walking shoes 'cos look cleats aren't going to be any good on the Beulah to Newbridge road.... 
Not that many roads out of Llanwrtyd so there's a bit of repetition - you get that particular delight 3 times in total.
Whislt I've ridden nearly all the revised route I wasn't brave/daft enough to try it all in one go at this time of year. Leg 2 was done on the tandem with panniers over 4 days. I'd say this leg has got easier - the lumps from Aber - Carmarthen have been replaced with an easy run down the Tywi, and the endless rollers of the A487 from Cardigan - Aber have been replaced with a run up the Teifi to Llandysul, then a big climb up Mynydd Llanllwni. St Clears - Cardigan is as before and just as viciously lumpy as I remember it.
Leg 1 gets both longer and harder as the flat run down the coast from Penrhyndeudraeth - Aber has been replaced with Trawsfynydd - Dolgellau - Mach - Llanidloes - Newbridge.
Leg 3 is shorter but about the same in difficulty. Slightly easier as MV says with Epynt instead of the GP. Hilly all the way round though.
The final leg home is harder as well as the long drag up Plynlimon and then the easy run down the Severn valley has gone, replaced by a couple of long gradual climbs from Llandod to Knighton. The last 60k is a sting in the tail though as there's a couple of monsters over to Clun then up the Onny valley to cross the Long Mynd before the last 20km of fabulous descent to U.M
