This talk summarises results from lattice simulations of N=1 supersymmetric Yang-Mills theory for the gauge groups SU(2) and SU(3). It is expected that this theory has a phase with broken chiral symmetry and non-vanishing gluino condensate. I will discuss the first exploratory studies of the gluino condensate with the gradient flow. If composite operators of bare fields are evolved along a trajectory on field space by means of the flow equations, they become renormalised up to a multiplicative renormalisation constant for the fermionic fields. This allows to calculate the topological charge, chiral condensate and energy density in terms of bare flowed fields on the lattice. We begin exploring this technique by measuring the finite temperature behaviour of the gluino condensate.
