Cool start, warming finish

Runners will face a cool start at 44°F that warms to 56°F at the finish, with a light wind from the SW at 6 mph. Humidity is moderate at 47%, making hydration essential as temperatures rise. The toughest segments will be between miles 5 and 11 with consistent headwinds, while the finish will be notably warmer than the start. Runners are advised to pace conservatively early on and stay hydrated throughout.

The finish is 20 miles from the start, so we look at it at 2 points, not just the start line. In a typical year, at 9:00/mi, you start at 44° and finish around 10:25 AM in 56°.

About the Lakeside Marathon

The Lakeside Marathon starts at Lakeside Beach in South Lake Tahoe, California, and finishes in Incline Village, Nevada. The course climbs from about 6,230 feet at the start to roughly 7,000 feet at Spooner Summit near the halfway point, then descends to near lake level around 6,300 feet at the finish - the first half is uphill, the second half is downhill. It is the Friday marathon of the three-day Lake Tahoe Marathon weekend (the "Tahoe Trifecta"), with aid stations roughly every four miles.
