As part of the Herschel Multi-tiered Extragalactic Survey we haveinvestigated the rest-frame far-infrared (FIR) properties of a sample of morethan 4800 Lyman Break Galaxies (LBGs) in the Great Observatories Origins DeepSurvey North field. Most LBGs are not detected individually, but we do detect asub-sample of 12 objects at 0.7 < z < 1.6 and one object at z ~ 2.0.  The ones detected by Herschel SPIRE have redder observed NUV-U and U-R colorsthan the others, while the undetected ones have colors consistent with averageLBGs at z > 2.5. The UV-to-FIR spectral energy distributions of the objectsdetected in the rest-frame FIR are investigated using the code CIGALE toestimate physical parameters. We find that LBGs detected by SPIRE are highmass, luminous infrared galaxies.  It appears that LBGs are located in a triangle-shaped region in the A_FUV vs.Log L_FUV diagram limited by A_FUV=0 at the bottom and by a diagonal followingthe temporal evolution of the most massive galaxies from the bottom-right tothe top-left of the diagram. This upper envelop can be used as upper limits forthe UV dust attenuation as a function of L_FUV}. The limits of this region arewell explained using a closed-box model, where the chemical evolution ofgalaxies produces metals, which in turn lead to higher dust attenuation whenthe galaxies age.
