Changing STW to an xc racing mag will never and should never happen. However, from some comments in this forum people could find it interesting to read. Especially if it opens up a dicipline that previously they had never tried (or not knowingly). If a feature gets people to try out a local xc race, then fantastic: its poeple out enjoying their bike.
Trail types: xc races typically use man made trails but with no ‘trail centre’ finish. The organisers use natural features and soil, of course there are exceptions.
If this thread has demonstrated one thing, it seems to be the lack of awareness/knowledge/experience of xc races.
Training ise, phil pearce is full time this year and typically rides for 2-3hr a day. A lot of which is on the mtb and off road. Riding on the road doesnt develop the muscle groups you use on the mtb.
