hi I graduated c25k about 3 weeks ago, I have done a few 5 k's 2 parkruns and 2 6 km runs and 1 7 k run. I noticed there is a 6 mile trail race at a nearby woodland in the evening on the 3 rd of June. I am tempted to enter, but wonder if that is too soon. I also swim and cycle regularly so am not too unfit, but 7 k is the furthest I have ever run up to now . Any advice on whether I should try it or not?
