During his tenure as an Instructor for Budokan South Africa he had to travel extensively throughout the country teaching at the many satellite Dojos.
There were many smaller clubs in the Durban area and these included schools such as Kearsney College, Saint Marys Girls College, George Campbell Boys College. He also taught Karate at the Durban South African Police Club.
In between these he had also to travel to many of the smaller country towns where there were members who wanted to learn. These included Bethlehem, Bloemfontein, Port Elizabeth , East London, Springs, Pietermaritzburg, Eshowe and as far afield as Potgeitersrust in the far north of what is now Gauteng.
Sensei Wridgway also played a large part together with Doshu Salmon and Shihan Ray Ryan in the development of the Budokan teaching and Grading Manual which is still in use today.
In 1968 Doshu Salmon started the Mountain Leadership School in the Drakensburg Mountains of the Eastern Free State. Sensei Wridgway was also involved as a mentor and Teacher.
In 1971 he opened a Budokan Dojo in Uvongo where he was living at the time .
This small club was very successful and in fact is still running albiet under a different name and style.
In 1977/79 He also ran small classes in Pinetown and Hammersdale and Port Shepstone.
Sensei Wridgway also taught at non white Dojos which at that time was not allowed. Some of these still thrive today.
He has sat on many many grading panels, workshops and Gashkyus over the years and passed his knowledge and expertese of the Art to students throughout the country.
In his spare time he has also managed to run the grueling Comrades Marathon (twice) and the famous Two Oceans Marathon. He was also placed 4th in his age group (55/60) Midmar Mile.
Although Derrick (Dix) is now retired he is still very much involved with all matters Budokan on a Daily basis,
He and Doshu Richard Salmon are firm friends which has spanned some 56 years
In a break from Karate he proved his determination to excel in whatever he undertook and completed the very challenging International "Two Oceans Road Marathon" which runs between the Atlantic and Indian Oceans around Cape Town and then he went on to complete in "two" of the World Famous Mega "Comrades Marathon", said to be one of the toughest road races in the world, both proud achievements..,
