75 days to run sub-40 at ASICS LDNX. Here's how.

Start the training that gets you there.

Your sub-40 10K It's within reach — but 75 days of the right training is what turns the possibility into your result.

That's where Runna by Strava, our Official Training Partner, comes in. Your predicted finish time is calculated from your current fitness — then every session is personalised to move you toward sub-40 at Wembley.

The 3 things to focus on now to run sub-40 at LDNX:

1️⃣ Make goal pace feel automatic.

Sub-40 will only feel controlled on the day if you've built the speed endurance to back it up. On LDNX's fast course, the runner who's trained to hold that pace is the one who carries it to the line.
💡 Runna's interval and threshold sessions develop the speed endurance your sub-50 goal demands, so race pace feels like second nature — not a fight.

2️⃣ Build the endurance that shows up at 7K.

The closing kilometres are where a sub-40 is sealed — and with the right endurance behind you, that's exactly where you'll feel strongest, powering toward the arch while others fade.
💡 Progressive long runs and mileage that increases at the right rate give you the strength to hold your goal pace all the way to Olympic Way.

3️⃣ Stay consistent — it's what compounds.

75 days of steady, well-recovered training beats a handful of big weeks every time. Easy days have to stay easy so you absorb the hard ones.
💡 Personalised pacing insights keep easy runs easy, and your plan adapts when life gets in the way — so you keep progressing.

75 days is the perfect window to lock sub-50 in — but only if you start now.
