I ran 3:51 off pure aerobic volume, no 1500m-specific work at all. Once Chris layers in 400 reps, race-pace sessions, and lactate tolerance work, 6 seconds is well within reach. Of all my goals, this is the one I'm most confident about.
Multi-year project. I'm 23, 1500m runners peak around 27-30, so the window lines up. I've built a big aerobic engine with very little speed work, which means there's a lot of upside still sitting in the tank once I actually train the event. 3:36 needs ~56-57 second laps, held. I'll need sub-50 400m speed and fast European fields with rabbits to get there.
18 seconds is a lot. But I'll be 29 in 2032, prime middle-distance age, and competing for Argentina rather than South Africa shifts things considerably. Argentina doesn't have a deep 1500m field. If I hold the national record and rank high enough, I could be their guy. The path is through the entry standard or rankings, not a brutal national trial. Whether my ceiling is 3:36 or 3:30 is a question nobody can answer yet... not until I have 3-4 years of proper speed and endurance work behind me.
Probably the most viable long-term goal of the lot. Runners who come from high-volume track backgrounds tend to do very well when they transition to trail. If I'm already at 115km weeks at 23 and my body is holding up, the durability is there. The UTCT 23km each November keeps the trail-specific work ticking alongside the track season.
