The sea swim takes place in Tywyn, where a triangular circuit will be established in the boat launch area adjacent to the Golden Sands building (Warwick Place/Marine Parade).  Wetsuits are mandatory.  The Caderman sprint distance is one loop of 600m.  For the Caderman Extreme 70.3 Athletes, its three loops, totalling 1900m.  In the event of heavy seas, the swim will be held indoors.




The Caderman Sprint route and the 70.3 Extreme route will see you riding out of Tywyn along the flat straights to Bryncurg, where you will turn to join the B4405.  Passing through Abergynolwyn you will soon be at the beautiful Lllyn Mwngil Lake.  Shortly afterwards, the two route diverge.  At the Minffordd junction the traditional sprint route turns left, A487 north, to take on the first major climb of the route, the Talyllyn pass is long and though it starts off with a steep left hand bend, the gradient is challenging but rarely enough to get you out of the saddle.  From there, the traditional sprint route descends via Tabor, to Dolgellau and then climbs the short but steep Cader Road to T2 at Ty Nant.

The 70.3 Extreme route, turns right at Minffordd, A487 South, and climbs to Corris before a long decent to Dyfi bridge.  From there its the A493, a beautiful route as you follow the Dyfi estuary to Aberdyfi, before riding parallel to the coast to get back to Tywyn and rejoining the traditional route noted above.


T2 sits at the foot of Cader Idris, and for those on the traditional Caderman sprint route, its merely a 5k run up the brutal climb of one of Snowdonia’s finest mountains.  The gradient is unrelenting as you tackle the Ty Nant Pony Path route to the summit of Cader Idris at 896m.

If you’ve opted for the Caderman Extreme 70.3 route, you’ll be running with your back to the mountain as you descend through the beautiful Gwynant Valley.  You will cross the A493 to join the award winning Mawddach trail, a former Railway line that takes you on a perfectly flat gravel path to Dolgellau.  From the Marian playing fields you climb the Cader road by foot, back to the Ty Nant Pony Path trail.  The final 5km is an un-relenting ascent of Cader Idris.
