Bud Baldaro. Former UK Athletics Marathon coach and personal coach to Hannah England, World Championships Silver medallist in 2011 and to many British international runners
As a coach for many years at club, student and area/international level David knows his stuff. Having known David for many years, I never fail to be impressed by his thirst for knowledge of the sport.

A student of the sport for numerous years; he is a true aficionado of the road scene. Passionate and inspired by runners of all ability levels he brings to the table a life long  love of the sport combined with a depth of knowledge and the ability to develop his points in a rational, accessible and comprehensible manner.   He possesses a genuine insight into the both the needs of runners and their patient progression plus of course the very specific demands of the event

David has shown tremendous intuition and drive to establish himself within the world of endurance running, not just as a respected coach but also helping athletes with races and training trips abroad. In wanting to help athletes he has actively sought information and advice from the best, not just in the UK but world-wide. He is now in a position where he can use this knowledge to help his growing band of athletes achieve their potential

David Chalfen is one of the most committed and passionate coaches I have met. Accepted coaching dogmas are challenged and his thirst for new approaches is ongoing. This couples with a sensitivity for the individual athlete's needs in terms of training/competition and lifestyle. In my opinion, he will undoubtedly be a coaching asset in the UK for the emerging generation of endurance athletes
