There are many courses where this will not work. Most courses do multiple loops and have portions where runners go different directions.
I was thinking about this a couple weeks ago when I first heard the idea of a time trial start for XC. It is an issue that would need to be solved, but I think it's solvable. Probably requires a few more Course Monitors, and they would definitely need to be trained a lot better than I see at a lot of meets so they're not just standing around on the course, they're actually doing something to help keep racers on course.
The reason I think it's solvable is I XC Ski raced in high school and college, and we also had course with multiple loops and split points that sent racers in different directions at different parts of the race. I was racing back in the 1980s, all of the ski meets I did were interval start (except the relays) - we didn't have any mass start races like they sometimes do in high school and college today. I never went the wrong way in any of those races and neither did any of my teammates. Then I coached college for 11 years and in that entire time we didn't have anyone go the wrong way and get DQ'd in the entire field in any of the races my team raced at.
Then I got thinking, well, what about the races the XC team I coach now went to last fall? Anything confusing on the courses?
--1st meet of the season was 2.5k out with no way to get off course, then an "upper loop" that was a little over 2k that you did twice, then left turn out of that loop and 1k to the finish line, again with no way to get off course. Nobody's taking any wrong turns on that course.
--2nd meet was 1k around an open field keeping the turn flags on your left shoulder, followed by a 3.5k loop that you did twice. No way to go wrong on that course.
--3rd meet was a 2k inner woods loop following by a different 3k outer woods loop done twice. The last 400m of both loops was the same. No way to go wrong on that course although there were a bunch of side trails on the 3k loop that you'd have to block off.
'--4th meet was a 2k loop that the racers did 4 times. The start ran 100m to get to the loop, and the finish was 50m off the right side of the loop. No way to go wrong.
--5th meet was a 2.67k loop that the racers did 3 times. The start and first 400m were to the left of the loop (inside) because it was wider there, and then you merged into the regular loop. No way to go wrong, although the men's and women's course did have one section that was different (men added on a 50m bump and women cut off a section on the first loop out to get the right total distances).
--6th meet might have been a little tricky. Belmont Plateau, Philly. It was 1.5k around a field, no way to go wrong. But then in the woods it was a figure 8 with a cross-over, then you went back and did the 1.5k field again. Then you did the lower part of the figure 8, and then the 1.5k field again to finish. Easy to get right in a mass start, but I could see this being tricky on an interval start format.
Having seen a lot of courses over the years, designed more than a few (and a few XC Ski race courses too), I would say most XC courses I've seen wouldn't be an issue with a time trial start. Some would, guessing maybe 10-20%.
One thing that would make is easier for course management, and would make it easier for meet personnel to help racers stay on course, is if racers started in bib order. Doing that, Course Monitors and the finish line should see somewhat of a steady flow of bib numbers, 1 first 2 second, etc etc. Of course you'll get some switching around as faster runners catch slower runners. But if a CM or the finish line is seeing bibs #1-20 mostly, and bib #50 comes along, that's a red flag. Let's say 1 starter every 10 seconds, unless #50 is clearly much faster than every else who has come along, it's a red flag to question if #50 really made up 5:00+ on the 1-20 bibs or if #50 missed a 1.5k+/- part of the course. It would be a good idea to have a couple of people at strategic parts of the course writing down bib numbers (or chip mats there) that can be checked afterwards if there is a question about a racer not doing the full course.
I don't like the idea of this kind of a fundamental change to the sport of XC, but if that's what we need to do to have a season this fall then I want to try it.
