So, here's my bike all set up to go for bikepacking:
On the front is a 20 litre Apidura pack containing a lightweight sleeping bag, mat, down jacket and (merino) clothes for sleeping in. On the back is a 14l Apidura pack containing an assortment of bits (food, coffee, bivi bag, tarp, pegs, trowel, small towel etc). If I was out on my own I'd also have a stove in there, but that was on the other guy's bike. I also had a small Camelbak with my usual ride stuff in there (first aid kit, tools, tube, bit of money etc) as well as a lightweight water filter. I think I'm also going to get a "fuel pod" which is a little bag that sits just behind the headset for snacks etc.
Despite carrying a reasonable amount of weight (at least 10kg between my back and the bags on the bike), it didn't actually feel too bad to ride, especially when I got used to how it handled. We did some very technical off road terrain and aside from the bike taking a bit more of a hit on dropoffs, it felt fine. In reality I should have upped my fork and tyre pressure a bit, but I just didn't think about it before going out.
Was a good ride on the whole, amazing scenery. Even got to look at a few bothies, which I didn't even know we had in Wales.
Plus we saved a lamb, which is always gratifying.
Slept under a tarp which had been set up completely open on one side, with the back edge to the wind. Weather wasn't horrible, but it did get pretty windy at times, and at about 4am it rained fairly heavily... which was good, because it was only at that point I finally managed to get to sleep. I generally sleep on my face at home so I found it particularly difficult to get comfortable in a bag / bivi. I think I'm definitely going to take a pillow next time as trying to use my down jacket as one really didn't cut it.
So yeah, just got to buy some extra bits and bobs now ready for my three day event at the start of May. I'm still fairly nervous about it, but less so than I was. I'm aiming for around average about 6mph moving average as a nice, sustainable pace... I just really, really hope I don't end up cycling in the rain as it's a whole different ballgame when you don't have somewhere warm and dry to end up.
