I am really looking forward to this. did the MDS this year, walked 75% of the thing, but managed to get the Ultra Race peaks and Chester Marathon on between then and now, so feeling good about it. I am looking forward to the more relaxed air there will be compared to the MDS, which was pretty full on.
I find calf gards more effective than tights, going to go for some ones just for the thighs as well. I find all over tights much less comfrtable, the seperate "units" seem to provide more compression also.
I find that wearing 2XU calf gaurds means my legs feel more refreshed after running, I also try to keep them on after evening runs for the dog walk.
