Is Jack and Jill's a Good BQ Course?

Published August 19, 2026 · Estimates, updated each registration cycle

Short answer: yes, and for a reason many runners get wrong. Jack and Jill's Downhill Marathon in North Bend, Washington is one of the most productive qualifying races in the country, and despite the word Downhill in its name it is not steep enough to trigger Boston's new time adjustment. The course drops roughly 882 feet net, from about 2,578 feet at the start to about 1,696 feet at the finish. Boston's threshold for 2027 is a net drop greater than 1,500 feet, so a Jack and Jill's time is submitted at full value.

Why the downhill reputation is misleading

The race is widely lumped in with the REVEL series and other canyon descents, and it is easy to see why: it markets itself to qualifiers, and a large share of its finishers do run Boston times. But the elevation math is a different category entirely. The steep canyon races drop 3,000 to 5,000 feet. Jack and Jill's drops under 900 feet net across 26.2 miles, an average grade so gentle that most runners describe it as flat with a long tilt. Total descent is around 1,300 feet against roughly 267 feet of climbing, so even the gross figure stays modest.

This matters more than usual for the September 2026 application window, because that is the first cycle in which the BAA applies its index adjustment. Courses dropping 1,500 to 2,999 feet have 5:00 added to the submitted time, and courses over 3,000 feet have 10:00 added. Jack and Jill's sits far below the first tier and is untouched. If you have been assuming your tunnel qualifier would be discounted, it will not be. See the list of affected courses for the full picture, and the downhill rule explainer for the mechanics.

What the course is actually like

The route runs on the Palouse to Cascades rail trail, a smooth, hard-packed gravel surface, and passes through the Snoqualmie Tunnel in the opening miles. The tunnel is dark, cool and just over two miles long, and a headlamp is required. Rail grades are consistent by design, which is exactly what a qualifying attempt wants: no surges, no steep pitches, and no late climb to blow up a paced effort. The profile is often summarised as half flat and half gently downhill, which sets up an honest negative split rather than a free ride.

The trade-offs are real. Gravel is slightly slower than asphalt and less forgiving if it is wet. The field is small, in the hundreds rather than the tens of thousands, so there are no large pace groups and you may run long stretches alone. The tunnel section costs a little time while your eyes adjust. None of this outweighs the profile, but plan for an even effort instead of expecting the course to hand you minutes.

Timing in the qualifying window

Jack and Jill's is a late July race, which places it just weeks before Boston's Qualifier Week of September 14 to 18, 2026. That makes it a genuine last chance to bank or improve a time for the 2027 race, with almost no margin left for a second attempt if it goes badly. Treat it as the closing option rather than the opening one, and see the last-chance qualifier calendar if you still need a backup.

Verdict

Jack and Jill's is a strong, fair BQ course: a consistent grade, a fast surface, full value under the 2027 rules, and a date that still counts for the coming registration. What it will not do is fix a thin buffer on its own. Our central estimate for the 2027 cutoff is about 5:15 under the standard, and that is an estimate rather than a BAA figure, so target a buffer with room to spare. Run your time and age through the predictor to see how your buffer would have fared against thirteen years of real cutoffs.
