First time poster so hopefully this is in the right section. I'm all booked up to do Tour du Mont Blanc in July. I'd class myself as relatively fit, I keep active, mainly been cycling (commuting to and from work ~15 miles 2-3 times a week with a 40+ mile ride on a weekend up to ~80 miles) however in the last year or so I've really began to enjoy walking again and the bug has well and truly bitten me. My longest day so far has been 30 miles and I've done multi day efforts of around 20 miles for 4 days in a row but both of those were relatively flat in terms of elevation in comparison to what will be ahead of me.
I'm under no illusion however that the best way to train for TMB is to get out there and get walking up some hills. However as I live in the South West (Bristol) I feel my options are relatively limited to get hill fit unless I am able to travel further north which will get expensive quickly (I am not earning big bucks sadly lol). I will have the opportunity to both do Snowdon and at the very least one or two day hikes in the Lakes in the coming months but those are one time deals thanks to piggybacking lifts with friends travelling north.
The most obvious choice would be to go to the Brecons which I have been doing as often as time and money allows (I can usually afford go out to once or twice a month) but I was wondering if anyone had any other suggestions where might be good to go and train a little closer to home. Any advice will be very much appreciated
