Blood donation marathon

This April 21 and 22, you have an appointment that could change everything. Once again, we are joining forces with La Paz University Hospital to promote the Blood Donation Marathon, a unique opportunity to do something great with a very small gesture.

For two days, the central square of La Paz University Hospital will become a space dedicated to solidarity, where healthcare teams will welcome all donors in a comfortable, safe, and well-prepared environment.

The schedule will be from 09:00 a.m. to 09:00 p.m., continuously, to make it easier for everyone who wishes to take part. Donating blood is a quick process — just 30 minutes — and completely safe, yet its impact is enormous: a single donation can help up to three different people.

At Caleido, we remain committed to this cause, actively supporting this initiative and encouraging our community to be part of something that truly makes a difference.

This year, we invite you to take it one step further:
be part of the change, donate hope.

Because every person counts.

Because every drop matters.

Because donating blood is giving life.
