Black Lungs
Cabot Trail Relay
Course difficulty by leg
Historical context (archived field through 2026): higher leg percentiles mean faster splits versus the full field on that leg. Value Added is optional deeper team history — how someone compared to past Black Lungs work on the legs they actually ran. Positive Value Added is above that baseline for the leg and year. Value Added
Batch-relative route profile scores from AllTrails-exported course recordings (same route-analysis heuristic): three 0–10 dimensions (endurance load, climbing severity, profile complexity), weighted overall score, per-axis ranks (1 = hardest among the 17 legs), a route-character label, and nominal leg start from the organizer leg-description PDF (America/Halifax). Descriptive only — not a predictor of race splits.
| Leg | Nominal start (Halifax) | Overall rank (1 = hardest) | Overall score (0–10) | Endurance load (0–10) | Climbing severity (0–10) | Profile complexity (0–10) | Endurance rank (1 = hardest) | Climbing rank (1 = hardest) | Complexity rank (1 = hardest) | Route character |
