Quality hurdling in Swindon

Popped up to Swindon to see my hurdles coach on Sunday, with the British Masters coming up at the weekend it was time for a bit of quality hurdling at pace.
My session was 2 runs over the first 7 hurdles and then 1 over 5. Experimenting with stride pattern on each run.

First run I went with 17 strides (left leg lead all the way) and raced against Jamie. I have the raw speed now between the sticks, but 3/4 and 5 were ugly.
Next run I went for 16s to 5, then 17s. Which means right leg over 2 and 4.
Hurdle two was OK, but 4 was dreadful, too high and lack of any momentum which meant I was struggling to make the 5th.
Last run just to 5. 17s to 3, then 16s to 5. This meant easing off over the first couple of jumps and then picking up the tempo in the straight. This was OK, but I still struggled over the 4th on my right leg lead. Still too high.
I think I need to spend some time on the right leg as the benefit of getting even just one right would be huge.
Will see how the week goes and the weather on Saturday before deciding on a race strategy.
Looking forward to Birmingham.
