Who are the top runners to watch at this Saturday's Divisional Championships at Wickham Park? Griffin Ott, a Darien High junior, has come up with a fairly accurate system where he uses a spreadsheet with times from each runner's invitationals and a few dual meets. He uses the runner's best times from the season and converts it based on course difficultly. All of the times are converted to times comparable to Wickham Park, a challenging five-kilometer terrain that is also the site the State Open on Nov. 4. His course conversion is based on other courses and their difficulty to Wickham.
