VIA Marathon: Pacing & Race-Day Strategy
A gentle net-downhill point-to-point down the Lehigh Valley, and a quiet PR specialist.
- Where:
- Allentown to Easton, Pennsylvania
- When:
- Sunday, November 15, 2026
- Course:
- Net downhill · point-to-point
- Best run as:
- Even pace
Heads up: the race is now the St. Luke’s D&L Marathon, run by the Delaware & Lehigh National Heritage Corridor, and it has moved from September to November. Same D&L towpath, new name and date.
Course & elevation
VIA runs point-to-point from Allentown to Easton, shedding a few hundred feet net as it follows the Lehigh River, much of it on the smooth, traffic-free D&L towpath. The descent is gentle and steady rather than steep, so it feels fast without pounding your quads. A few short rolls break up the riverside miles, but nothing that earns the name of a hill.
- Start → Finish
- 380 → 255 ft
- Net
- −125 ft
- Total gain
- ≈ 125 ft
Key moments
- Mile 1–5Road miles out of Allentown that ease downward. Relax and let the grade carry you.
- Mile 8–22The Lehigh River towpath: flat, shaded, and remote; lock into goal pace.
- Mile 24–26.2A short rise back to roads before the finish in Easton.
Pacing strategy
Run even effort and the gentle descent will reward you with a slightly negative split. The towpath is quiet and lonely, so be ready to do your own pacing work without crowd energy through the middle.
Pacing by goal time
Checkpoint splits for four common goals at VIA Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.

Grade adjustment is a model, not a promise. It assumes even effort and ignores wind, heat, and how well your legs handle sustained descent — which on a steep course is often the deciding factor.

Fueling & hydration
Aid stations come roughly every two miles, but the remote towpath sections make it worth carrying your own gels as backup. Fuel on a fixed 30–40 minute schedule so the unhurried river miles don’t lull you into skipping one.
Weather
Mid-September in the Lehigh Valley is typically cool at the start, with the riverside shade keeping things comfortable even on a warming day.
Is VIA Marathon a good Boston qualifier?
Yes. The course drops 125 ft net, comfortably inside the 1,500 ft threshold where Boston's downhill adjustment begins, so a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
