    Lon Las Cymru - Wales - anyone done this?

    Next Thursday 3 friends and I are tackling the Lon Las Cymru, the cycle route through Wales starting at Holyhead in the north and heading down to Cardiff in the south.

    Despite the route being broken into 8 stages and being 'perfect for a weeks cycling' we've got 4.5 days to do it in.

    This means that on most days we'll be doing about 50 - 60 miles, but with over 1000m of climbing on 3 of the days.

    Here's our intended itinerary, I'd be happy to hear anyone's thoughts or advice espeically anyone that's done this ride themselves.

    lonlas2008v3.gif

    Thursday: Holyhead - Caernarfon (30 miles - 3.5 hours)
    Holyhead - Menai bridge - direct on the A5 - 22miles / 2.5hrs / 320m ascent
    Menai bridge - Caernarfon - NCN8 - 8.5miles / 1h / 70m ascent

    Notes:
    * pretty flat and fast, mostly road surface.
    * The A5 route will save us about an hour on the sustrans route and allow us to get into Caernarfon in plenty of time for dinner.


    Friday: Caernarfon - Barmouth (51miles - 8-9 hours)
    Caernarfon - Penygroes - Portmadog - 29miles / 4h / 480m (steep ascent out of Criccieth) (shortcut 20miles /3h)
    Portmadog - Barmouth - 22miles / 4-5h / 620m (some very steep gradients before flatter ride to Barmouth)

    Notes:
    * there is 1100m of climbing today.


    Saturday: Barmouth - Llandidloes (61m - 8-10 hours)
    Barmouth - Dolgellau 10miles / 1h /20m
    Dolgellau - Corris - Machynlleth - 28miles/ 3-4h/620m (route now takes to hills with significant cumulative ascent)
    Machynlleth - Landidloes - 23miles/4-5h/780m ascent (mountain road climbs to 509m)

    Notes:
    * 1400m of climbing - it's the start of the big hills.
    * out of dolgellau 7km ascent first 2km steep followed by steep bits then 180m in 1.6km (10%+). Then 4km downhill, then up and down before run down into machynlleth.
    * from Machynlleth there is a gentle ascent for 4km, then starts in earnest with 400m climb in 7km. false summits and steep sting in the tail.
    * 5km descent is a joy


    Sunday: Llandidloes - Brecon (64miles - 11 hours)
    Landidloes - Rhayader - 15m/3h/490m
    Rhayader - Builth wells - 17m/3h/430m
    Builth wells - Glasbury - 16m/2h/190m
    Glasbury - Brecon - 16m/3h/360m (one significant and steep ascent)

    Notes:
    * biggest day of climbing with over 1 mile today!
    * A long day of cycling but not very far which means lots of hills.

    Monday: Brecon - Cardiff (52miles - 7-8 hours)
    Brecon - Merthyr - 23m/4-5h/540m (a major ascent and descent)
    Merthyr - Cardiff - 29m/3h/90m (easy cycling)

    Notes:
    * A hilly start then a gentle 30 miles into Cardiff for a celebratory drink and the train home.

    Haven't done it, but it looks like fun! Assuming you're well-trained and geared for climbing...

    I've done it 3 times, once from holyhead to cardiif and twice from cardiff to the north of Wales.
    It is very nice and scenic. Some parts of Wales are very hilly, bring the low gears.
    I cycles about 80-100 km a day.
    Wales is maybe my favorite parts of the UK for cycling.

    I'm really looking forward to this ride, but haven't done nearly enough training, so I've opted for some mechanical help. I've changed my chainset for a 22/32/43 from a 28/38/48 to give me some help in the hills.

    22/32/43 is much better than what I used the first time.
    I used a 42/52 chain set with a 12-23 cassette. I had to walk quite a few times
