Use PadRight with the cyclical padding setup:

funcs = {f1, f2, f3};
data = Range[1, 20];
MapThread[#1[#2] &, {PadRight[funcs, Length@data, funcs], data}]

or

MapThread[Compose, {PadRight[funcs, Length@data, funcs], data}]

{f1[1], f2[2], f3[3], f1[4], f2[5], f3[6], f1[7], f2[8], f3[9], f1[10], f2[11], f3[12], f1[13], f2[14], f3[15], f1[16], f2[17], f3[18], f1[19], f2[20]}
