Hello,
I write this like a "thank you very much" for your help...sorry for my poor English and if there is some misunderstood, it will be my English, sure.......I would like to write down it in more deep but it is hard explain ideas in other language....
I did about a 90% of the Highland trail 550 from 4 to 12 on this june...mainly, I did not ride the 30 km further north kilometers and I left (withdrow?? , scrachted??) at Fort William...that day (my nine day) at 11.30 am I was again completely wet and I saw the train station....and I took the train to Tyndrum.....
The route "on the paper" is hard but the conditions are the "hidden enemies": in my 9 days only two afternoons and one morning I saw the sun....rainy days, windy days or rainy/windy days were the common days... when i went to Scotland I knew about the scottish weather but....

...the soaked? ground is other factor....Some nights, fortunately there are bothies...oh my good!!...To finish the day wet and to have a bothie in the middle of no where...it has not price!!!..bivys are very hard with wet, very wet ground and if you are wet.....
I did it with a stove and a little pot and mostly I eated brought food (not café/bars/restaurants). For this kind of route, it is perhaps an excesive baggage....
The route is a superb route: an impressive succession of links of paths and tracks for some incredible, lonely and wild places...vaguely exciting and hard....and it is a challenge too. Ride that route with 8-10 kgrs loaded is a great challenge, huge challenge.....and the wind, it drains you....
In my opinion there is an excessive hike-a-bike / push ups...and I understand that it depends on the skills and kind of bike of the biker, even so, there are many non-cycling areas at all....and I understand that in 900 km of trails and tracks must be paths like that....
I have returned with a bitter feeling because I have not been able to realize it whole, but on the other hand, I have tried and realized for the most part a route of which its creators and guardians can be proud, very proud; because the route and because the wild and virgin nature by which it runs
summarizing: Highland Trail 550 is a challenge route, an impresive route to obtain your postgraduate degree in mountain bike trips in one of the most clean, wild, inhabited and superb scenaries in europe. Do not underestimate it because it is in Europe. Be careful and do not worry: scottish people will help you if you have some trouble, for sure!.....in spanish: Putos escoceses, vaya pedazo de ruta que se han cascao!! están locos!!! su puta madre!!
Thank you for your help, see you riding anytime, anywhere!!
P.D: This year, I followed the race on trackleaders and i have been cycling the route...then.....How can someone do it in less than 4 days?????!!!!!!!!!!......then....Congratulations to all the racers, really, it is "something important" start the race and finish it......bravo!!!
