I successfully 1-way unsupported ran the 1000 Island Waterfront Trail on Saturday, April 13, 2024, in the evening. I carried 2 bottles, 150mL of maple syrup, some gels, a headlamp, gloves, and snacks (for after the run) in my hydration vest. I consumed 500mL of Hoist, 400mL of water, 120mL of maple syrup, and one Clif Energy Chews pack, I roughly ate one block or one sip of maple syrup every 15 minutes.
It drizzled a bit at the very beginning, not enough to soak my clothes, but enough to get my socks wet. They mayflies were pretty bad, I had to run some segments looking straight at my feet, letting my cap/visor protect my face from the clouds of them. I'd get some in my mouth or eyes occasionally. Spit out at least a dozen of them.
I may return in the future to complete another attempt, but most likely supported in order to not carry a vest.
