i am so pleased that someone has said it's harder!
i've recently started running after a long layoff. now out in the countryside so all running is off road and hilly as opposed to nice canal paths and flat. even with my lack of fitness and extra weight and extra years i'm amazed at how slow i am! 10:40m/m when i at least thought i'd be at 9:45m/m or something (was around 9m/m before but was mainly just cycling).
anyway, i love it: the countryside, very few people and those you do come across are always others out enjoying the countryside. just bought a headtorch so i can carry on in the winter. trail shoes (addidas kandida?) make the running easier than the massive motion control shoes i wore on the road as i can kind of feel the track better and my feet don't get thrown off at weird angles. i was really suprised. also i really feel my lower legs strengthening. i hope that that combined with other strengthening work will help keep me injury free.
only thing i'm wondering about rather prematurely is what it'll be like running VLM after so much trail running? i guess a few road races will let me know how my legs respond and also give me a better idea of times i can expect. i guess i could run around the same mile of pavements in the village. don't fancy heading out on the roads though as they're pretty busy.
