  We establish the real integral Hodge conjecture for 1-cycles on various
classes of uniruled threefolds (conic bundles, Fano threefolds with no real
point, some del Pezzo fibrations) and on conic bundles over higher-dimensional
bases which themselves satisfy the real integral Hodge conjecture for 1-cycles.
In addition, we show that rationally connected threefolds over non-archimedean
real closed fields do not satisfy the real integral Hodge conjecture in general
and that over such fields, Br\"ocker's EPT theorem remains true for simply
connected surfaces of geometric genus zero but fails for some K3 surfaces.
