60K • Flagship Ultra
For experienced mountain runners seeking deep climbs and long estate traverses.
Begins in the pre-dawn mist, climbs to panoramic ridges, and threads shaded coffee blocks. Long runnable descents reward patient pacing.
- Recommended: a recent 45–60K trail finish or strong road marathon background.
- Aid every ~8–10K with water, salts, basics; carry 1L minimum and weather shell.
- Ideal prep: hill repeats + back-to-back long runs to mimic estate gradients.
45K • Classic Mountain Loop
A balanced ultra—punchy climbs, runnable flats, big coffee estate panoramas.
Perfect for marathoners stepping up. Alternates shaded climbs with flowing descents—maintain effort, not pace, and bank energy for late rollers.
- Recommended: sub-5:15 road marathon or prior 30–40K trail.
- Carry 750ml+, salts, and a light layer; mid-race sun can be humid.
- Focus on downhill form and poles (optional) for sustained control.
36K • Technical Estate Roller
A confident step beyond the half marathon with real trail texture.
Switchbacks through coffee and shola edges, short steeps, and runnable benches. Strong pacing early lets you cruise the late downhills.
- Recommended: recent half marathon (road or trail) and hill work.
- Carry 500–750ml plus salts; expect mixed shade and open sun.
- Practice hiking cadence—efficient power hikes save the quads.
18K • Intro to #ultramalaivasi
Gateway to trail running with scenery, climb lessons, and lots of smiles.

- Recommended: comfortable 10–12K road fitness.
- Carry a handheld or small vest; aid spacing supports new runners.
- Perfect as a family or crew morning before cheering later finishers.
