We investigate the consequences of combining swampland conjectures
with the requirement of asymptotic safety. To this end, we explore the infrared
regime of asymptotically safe gravity in a toy model, quadratic gravity at one
loop. We identify the hypersurface spanned by the endpoints of asymptotically
safe renormalization group trajectories. These comprise the allowed values of
higher-derivative couplings as well as standard logarithmic form factors. We
determine the intersection of this hypersurface with the regions of parameter
space allowed by the de Sitter conjecture, the trans-Planckian censorship
conjecture and the weak gravity conjecture under the hypothesis of
electromagnetic duality. The latter two depend on some order-one constants, for
generic values of which we show that the overlap region is a proper subspace of
the asymptotically safe hypersurface. Moreover, the latter lies inside the
region allowed by the weak gravity conjecture.
