Long cycling

Option A (moderate): South Platte Trail → Chatfield loop, 30–35 mi, mostly flat-rolling, 2.5–3 hr, Z2

Option B (climb-lite): Deer Creek Canyon out-and-back to South Valley Park (skip High Grade), 25 mi, 1,500 ft gain, ~2 hr

Pick by how Saturday's long run legs feel. Prefer Option A this week.
