Maggie, together with her partner Rob, did a lot for TREC in the early days, including forming the SE TREC Group many years ago.
They organised all of the routes for the twice yearly Tilford Riding Club TRECs and Maggie was promoting the sport.
They also organised some events near where they lived in Surrey, one of which went through their fields with the PTV on the route.
Additionally, they organised the English championships at Plumpton in 2004, with Rob spending several weekends building a staircase up and down a slope (which was still there a few years ago, when I last visited)
They also provided on the foot training and even did one after dark, providing a barbeque afterwards. Maggie still runs On the Hoof themed rides in Surrey.
