JC,
I have found schools will be interested once you run times in a zone they look for. Bigger schools recruit early so Junior years are important because after junior (grade 11) summer, the next time you will race hurdles might be indoors grade 12 year. My hurdler did not run great times as grade 11. I don’t think he was top 100 in his class that year. It was a great indoor season that got him noticed. Just keep training and getting better and finding races that you can run well at. It appears there is not a lot of competition around you. Seek out more races that might provide it, because it is likely you will run considerably faster.
I have “used” McFarlane’s tables too, but did not find them very valid for us. I found the first hurdle was quick and every hurdle after lead to really slow prediction times, which was not true, and double checked with my video touchdown analysis. You may find it works for you.
Reflecting back, I would say working to hurdle 6 at race pace with spacing is key. I noticed you mentioned endurance and thinking about going out to 400m. That might work in North Carolina where weather is nice 10-11 months a year. Where I am in Michigan, and you in BC, chances are that isn’t true.
For hurdle endurance outdoors, 5 step hurdling is highly recommended (I never used it) and also 12 hurdles. I can’t recall exactly but Aries uses a 12 hurdle workout as a “Race predictor”. Hitting a certain time leads to certain race times in 110H.
For working the first few hurdles, see if you can run next to a sprinter without hurdles. Maybe a fast girl or average boy. We did this a lot where I would have my 11.0 sprint do starts to 20m vs the hurlder (2 hurdles). He wasn’t challenged much out of the blocks and to work on getting out quicker this is how I arranged it. The more speed you carry into hurdle 1 the faster the subsequent hurdles will be and the more important the race model rhythm becomes.
Based on the 14.96 video, I would also suggest a more aggressive arm action to pull the trail leg through faster. On video, count frames to track flight times. The fastest we ever got was 0.30 for most of the race. His grade 11 year he was 0.33-0.36. You can see how improving 0.03 for 10 hurdles plus race rhythm improvements can lead to huge drops in times.
