Dvostruki svjetski F1 prvak Fernando Alonso odvozio je najbrže vrijeme na prvom slobodnom treningu za prvu utrku WEC supersezone 2018./2019. na Spa Francorchampsu.
Alonso je u Toyoti TS050 Hybrid #8 postavio najbrže vrijeme dana 1:58.392, odmah nakon što je automobil preuzeo od suvozača i bivšeg F1 vozača Sebastiena Buemija.
Alonsov najbrži krug bio je jednu desetinku sekunde brži od Buemijeva i 0.237 sekundi ispred drugoga Toyotina LMP1 automobila #7 u kojem je najbolje vrijeme odvozio Mike Conway.
Najbrži od privatnih LMP1 momčadi bio je #3 Rebellion R-13 s Gibsonovim motorom koji je bio tek 0.457 sekundi sporiji od Alonsa, a vrijeme je postavio Thomas Laurent pretkraj treninga.
Još jedan bivši F1 vozač Pastor Maldonado bio je najbrži u LMP2 klasi u #31 Oreca 07 Gibsonu s najboljim vremenom 2:03.494, 0.640 sekundi ispred drugoga najbržeg vozača u klasi Andrea Negraoa.
