Just ride the Sean Kelly schedule.
Paris-Nice, Milan-Sanremo, Critérium International, De Panne, De Ronde, Itzulia, Roubaix, Ardennes triple.
Kelly managed to win PN, Itzulia, PR and LBL from that schedule and came second in MSR and De Ronde.
Not so much beating around the bush (
Critérium International could be tricky as it isn't held, but oh well).
