In B1 enter:
=A1
In B2 enter:
=IF(A2=1,1+B1,0) and copy down
In C1 enter:
=MAX(B:B)

Here is an example:

0 0 5
0 0
0 0
0 0
1 1
0 0
0 0
1 1
1 2
1 3
1 4
1 5
0 0
0 0
0 0
0 0
0 0
1 1
0 0
0 0
1 1
1 2
1 3
0 0
0 0
1 1
1 2
1 3
1 4
0 0

Since C1 is 5, we know that there were 5 consecutive 1's somewhere in the
list.
