SRT Run Course Guide

The SRT Run 70-mile starts at High Point Monument in High Point State Park, New Jersey, not New York, before crossing the state line onto the Shawangunk Ridge Trail and finishing in Rosendale. It is fully unsupported: no pacers, no crew, no caches, and the checkpoints exist for safety accountability only, not aid. The race itself cites typically about a 50 percent DNF rate on the 70. I will walk you through the route first, then give you a pacing and fueling plan built for a self-navigated, self-supported day and night on trail.

The course: New Jersey to Rosendale, unsupported the whole way

The 70-mile follows the Shawangunk Ridge Trail from High Point Monument in New Jersey, north across the state line, and on to Rosendale, New York. The 30-mile starts fully within New York, at Sam’s Point Preserve in Cragsmoor, and joins the same route to the same finish. Both share the defining fact of this race: there is no aid on course, anywhere.

Self-navigation and a real state-line start

Say it plainly: the 70-mile SRT Run starts in New Jersey. High Point Monument sits inside High Point State Park, across the border from the New York trail system the race is named for. You cover real distance in New Jersey before the course crosses into New York and eventually reaches the Shawangunk Ridge proper. Do not plan your logistics, or your crew’s drive, assuming an all-New-York start.

You also navigate by trail blazes and map, not constant course markings the way a typical marked ultra runs. Know the route, carry a map, and do not assume you can zone out and follow ribbons the whole way.

Fully unsupported: what the 6 checkpoints actually are

The race is explicit about this: 6 staffed checkpoints exist for accountability and safety tracking only. No food, no fluid, no aid of any kind. No pacers, no crew access, no drop bags, no caches. Everything you eat, drink, and use to purify water along the way has to come from what you are carrying at the start, or what you legally resupply yourself outside of race support.

This single fact drives almost every other decision on this course: your pack weight, your water strategy, your calorie plan, and your pacing all get built around self-sufficiency first, speed second.

The ~50 percent DNF rate is the honest headline

The race itself cites typically about a 50 percent DNF rate on the 70-mile. That is not a rare bad-weather-year statistic, it is the normal outcome. Respect that number when you plan. It usually is not raw fitness that ends someone’s day here, it is running out of water, mistiming the navigation, or misjudging how much a fully unsupported 70 miles actually demands compared to a supported race of the same distance.

Pacing strategy for a self-supported evening-to-midnight race

With a Friday evening start and a midnight final cutoff, the SRT Run 70 is as much about managing a full day-and-night effort as it is about raw pace on the ridge.

Pace against the checkpoint cutoffs, not a flat-course time

The cutoffs at Route 52, Jenny Lane, Coxing Kill, and Spring Farm are spaced through the day and into the evening, which means you need to know where you stand at each one, not just at the finish. A vert-aware finish prediction and an honest look at your buffer at each checkpoint tells you whether you are actually on pace or quietly falling behind on unsupported, unmarked terrain where falling behind is expensive.

Build slack into your plan, not just your legs

Given the roughly 50 percent DNF rate, treat your own pacing plan as something with real margin built in, not a best-case line you hope to hold. Check your projected splits against each checkpoint cutoff well before race day, and know exactly how much time you can afford to lose to navigation, water stops, or a rough patch before a cutoff becomes a real risk.

Fueling strategy for a course with zero aid

There is no aid station handing you anything at the SRT Run. Every calorie, every liter of fluid, and your water purification method have to be part of your own plan from the start line.

Carbs and calories: plan for the full unsupported distance

Aim for roughly 60 to 90 grams of carbohydrate per hour as a baseline, then work backward to figure out what that means in food weight and volume for the full 70 miles you have to carry or legally resupply yourself. This is a logistics problem as much as a nutrition one: know exactly what you are eating at each hour of a run that can stretch well past 12 hours, and pack accordingly.

Water purification is not optional

You need a way to purify water on course, since the race explicitly expects it and provides none. Whatever method you choose (filter, tablets, or otherwise) test it on a long training run first, not for the first time mid-race. Combine that with sodium in the 300 to 700 milligram per liter range depending on conditions, and build your hydration plan around confirmed natural water sources along the route, verified ahead of time, not assumed.

SRT Run FAQ

Where does the SRT Run 70-mile actually start?

It starts at High Point Monument in High Point State Park, New Jersey, not New York, before crossing into New York and finishing in Rosendale. It is easy to assume this is an all-New-York race because of the name and the finish location, but the 70-mile course begins across the state line. The 30-mile race starts fully in New York, at Sam’s Point Preserve in Cragsmoor, and also finishes in Rosendale.

How hard is the SRT Run?

The SRT Run 70-mile is genuinely brutal, and the numbers back it up: the race itself cites typically about a 50 percent DNF rate. It is fully unsupported. No pacers, no crew, no caches, and the 6 staffed checkpoints exist for safety accountability only, not to hand you food or water. You navigate by blazes and map along the Shawangunk Ridge Trail and carry everything you need, including a way to purify water. This is not a course to underestimate because the elevation profile is not extreme; the self-sufficiency demand is what breaks people.

What does "fully unsupported" mean at SRT Run?

It means exactly what it says: no food, fluid, or aid of any kind at the checkpoints, no pacers, no crew access, and no drop bags or caches anywhere on course. You carry your full nutrition, hydration, and water purification for the entire distance, in the case of the 70-mile, over the course of a full day and night. Treat this like a self-supported backcountry effort with checkpoints, not a normal aid-stationed ultra.

How should I fuel for the SRT Run?

Because there is zero aid on course, plan your full nutrition and hydration around what you can carry and, if allowed, cache legally along public sections, and confirm the current rules before assuming anything is permitted. Most runners do well around 60 to 90 grams of carbohydrate per hour for the duration, with sodium in the 300 to 700 milligram per liter range depending on conditions, but the bigger question is logistics: how much weight you carry, how you purify water on course, and how you resupply calories for a run that can span 12 to 24-plus hours. Build your plan with the free ultra fueling calculator, then work out the carrying logistics separately.

What are the cutoff times for the SRT Run?

For the 70-mile: Route 52 by 11:30 AM, then shared cutoffs with the shorter distances at Jenny Lane/Route 44-55 by 4:30 PM, Coxing Kill by 6:30 PM, Spring Farm by 8:30 PM, and a final cutoff at midnight. With an evening start and cutoffs spread across a full day and night, pacing against the clock in the dark is part of the challenge, not an afterthought.

Is the SRT Run a good first ultra?

No. This is not a beginner race. Between the fully unsupported format, the self-navigation by blazes and map, the requirement to carry water purification, and a roughly 50 percent DNF rate on the 70-mile even among experienced entrants, the SRT Run assumes real backcountry self-sufficiency on top of ultra fitness. If you are new to ultras, look at a supported race with regular aid first, and treat SRT as a goal for once you have that self-sufficiency dialed in.
