Use findpeaks or islocalmax to find and isolate the peaks that describe the stride.

Use findpeaks on the negative of the signal or islocalmin to define the ‘valleys’ if that is how the gait states are described in the data.

if you define stride time as being the time between heel strikes of the same leg, so the stride time is diff(gait_data(hs))*deltaT (where hs is heel strike event, deltaT is 1/sampling_freq). Assuming you have identified gait events from your gait data.
