How about a customized marathon training plan?
You could provide him with a personalized marathon training plan designed specifically for him, based on his fitness level, running history, and goals. This would show that you support and encourage his passion for running, as well as demonstrate your consideration and thoughtfulness.
Another option could be to get him some new running gear.
Perhaps a new pair of high-quality running shoes, some moisture-wicking socks, or a lightweight and breathable jacket that can help him train outside in any weather condition would make a great Valentine's Day gift.
Lastly, you could consider signing him up for a virtual marathon.
With many races currently cancelled due to COVID-19, virtual marathons provide an opportunity for runners to still compete and challenge themselves. This would demonstrate that you not only support his love of running but are also willing to think outside the box for ways to keep him engaged with his passion during difficult times.
Or you can get him a star map with the date of your first kiss.
