This link below gets you to one of the best summary articles (actually guidelines) I've come across on lightning, very recently published by the Wilderness Medical Society. (Thanks, WMS!) Some of the treatment stuff is probably too technical medical; you can skim it or ask a friend working in health care to interpret it.
But there is practical straightforward stuff that ultrarunners can use (and if trying to make some buckle cutoff, maybe ignore, but at least it would be informed risk-taking.) Such as:
if one can hear thunder, then there is a risk of lightning strikes and one should seek shelter immediately. As substantial shelter is rarely available in the wilderness, hearing thunder in this setting should trigger an individual to immediately avoid or leave areas that are high risk for lightning strikes, such as ridgelines or summits, and to avoid tall objects such as ski lifts, cell phone towers, or isolated trees.Additional bonus learning point /editorial is in Table 1 "ACCP classification scheme for grading evidence and recommendations in clinical guidelines." In medicine, workup and treatment guidelines are rarely clear cut / black and white. Recommendations are graded; by the quality of supporting evidence. Often what gets done for patients (or asked by patients of their doctors) is low on that table. Aside from the impracticality of going in to the emergency department (or at least mine) demanding an MRI for your sprained ankle...
