Substitute for Variable Intensity Intervals

I’m training on the Marathon Level 1 plan and wondering what to substitute for the variable intensity intervals I have coming up this week. The challenge is this workout includes very short intense intervals (30 and 45 seconds), but I’m running on roads with occasional cross-traffic, turns, and potholes that require watching road conditions carefully–not the watch. This would be a great workout for the track, but that’s closed due to COVID 🙁

What would make a good substitute? It’s a speedy workout, so I’m thinking something like hill repetitions (RHR34) or tempo (RT43). Enjoying the plan–just don’t want to twist an ankle because I glance at the watch during a 30-second sprint. Thanks
