Royal Dutch League for Physical Education

The Royal Dutch League for Physical Education (Koninklijke Nederlandse Bond voor Lichamelijke Opvoeding or KNBLO-NL) was a Dutch sports association, focused on sporting and recreational walking.

[2] The resulting organisation has 100,000 members and is a major sports association within the NOC*NSF.

The League was established on 3 April 1908 as the Dutch League for Physical Education (Nederlandsche Bond voor Lichamelijke Opvoeding or NBvLO) by baron Frits van Tuyll van Serooskerken, lieutenant-colonel W.F.K.

It organised about 1,000 walking events a year, ranging from small-scale long-distance tours under 100 kilometres to large scale events such as the International Four Days Marches Nijmegen, the Red Cross 'Bloesemtocht' and the annual Avondvierdaagse.

[3] Its associations and volunteers also maintained a growing number of permanent walking routes.
